Seiyo Academy students
Japanese Voice Actress
Marimo Hatanaka is a fourth grader from the Star Class at Seiyo Academy. She appears in Episode 045, auditioning to play the accompaniment on the piano for the Choral Competition Seiyo Academy was entering. She becomes friends with Seiichiro Suzuki and helps him practice singing because he wasn't the best at it. She tells him her dream was to play the piano always, even after she got married and had children; hoping to play with them.
Marimo is only seen at Seiyo Academy which means she has the typical girls' uniform: a red plaid skirt, a blazer with a red tie and white shirt, and white socks pulled up so they were below her knees with black shoes. Unlike some of the other girls, though, she doesn't wear her blazer over her black vest, white shirt, and red tie.
Her hair is dark green and reaches below her neck and shoulders, and has a white headband in the front. Her eyes are brown.
Her X-Character looks like a typical one, black with a red "X" on their foreheads, but hers has a musical baton which she uses to send some of her attacks.
Her Guardian Character has blonde hair pulled up into what seems to be a ponytail; the ends split so that they come over to both sides of her head and has a pink eighth note on the left side of her hair. Some of her hair isn't pulled up into her ponytail and her eyes are brown. She wears an orange outfit with a white collar and white cuffs and, though very hard to see, what seems to be orange or pink shoes. Coming from the center of her collar is a scarf or a tie that's decorated to look like piano keys. She doesn't mention her name to Amu.
Not much is known about Marimo, but she is shown to love playing the piano and seems to be a nice person. She auditions to play the accompaniment on the piano for the song Seiyo Academy's students were to sing and lands the job, surprised she managed to get it. During their first practice, she's playing the piano and eveyone's singing, but there's one person who wasn't on key or the pitch and everyone stops singing and she stops playing the piano. It was Seiichiro who wasn't singing so well, so he apologizes and hides behind his music sheet, some people looking at him, including Marimo.
After Amu finds and talks to him before leaving, Marimo discovers Seiichiro behind some trees where, prior to, he had been practicing by himself. She tells him they should practice together, but he looks confused so she explains that it must be hard to sing without the accompaniment and that she would play for him. He tries to tell her he it was fine because he didn't want to bother her, but she tells him she had to practice anyway and says they should practice together. Seiichiro blushes and tells her he looked forward to practicing with her and bows, making her smile and telling him she was looking forward to it, too.
The same day, Amu is walking home from practice and hears a noise, so she Ran, Miki, and Su go check it out. They come to the room where practice sessions were held and find Marimo and Seiichiro playing the piano and singing, respectively. The song ends and Marimo tells him he did much better than before. She says that when he sang with confidence he would sound better than when he would when he hunched over all the time as his pitch would get off. He tells her he understands and bows, making her tell him he didn't have to be so formal since they were classmates. He tells her again that he understood, but not so formal that time, asking if it was alright that way. She tells him it was fine and asks if he wanted to do it one more time. He agrees with a smile as Amu listens to her Guardian Characters comment on how nice it was before she smiles, too.
Later, Seiichiro and Marimo are walking home, Seiichiro apologizing on keeping her out so late. She shrugs it off and says that she got to practice some also. He stops walking and hunches over, asking her if she thought he could sing well. She tells him he would be fine and says that singing well wasn't what mattered the most. He looks over at her, waiting for her to continue and she says that he should just have fun since the word "music" was written using the characters "fun" and "sound." She says there was no point in trying if you didn't have fun and he wonders if that was right.
Marimo turns to look at the scenery and says that she wasn't that good either. He tries to tell her otherwise, but she says she knew her music playing was okay. She goes on saying that she sometimes thought about how she wasn't that great and that she was jealous of the people who were great and would become professionals. She's about to tell him her dream, but stops to tell him not to laugh. He promises he won't and she tells him her dream was to be able to play the piano always, even after she was married, saying she wanted to be able to play with her husband and children every day. She blushes a bit, but turns around and tells him that that was her dream. He's shocked about the aspect of her getting married and she asks if that was weird, but he turns around and says it wasn't and tells her he thought her dream was a wonderful one. She asks him if something was wrong, but he tells her not to look at him.
The next day at school in their usual practicing place, Tadase is telling everyone that tomorrow was the actual performance, making the current practice their last. Tadase begins to conduct, Marimo begins to play the accompaniment, and the students begin to sing; most noticeably, Amu isn't looking as scared as she had the first couple of times. The students stop singing when Marimo messes up. She apologizes and asks if they could start over. Tadase says that they could, but a voice tells them that they couldn't. The students look at Saaya and the other four students not on stage as Saaya goes on saying that if Marimo messed up then, what was stopping her from doing it tomorrow? One of the girls next to Saaya says that Saaya should have been chosen instead as it would've been better. Tadase tells them it would be alright and tells Marimo that could start again from the top. Saaya's friends ignore him and go on, saying that if it were Saaya playing the piano, they would definitely win and get the prize.
Amu's Guardian Characters are noticing how mean Saaya and her group were being when Marimo apologizes again and says she would try harder. Another girl asks that even if she tried her best, it may not be enough, causing Marimo to gasp and Amu to step forward, but having Seiichiro beat her to it. Angry, he tells them that music was having fun with sound and that winning wasn't important as long as they had fun. Saaya asks that if they weren't in it for the prize what they were aiming for, and asks if it was just to participate, saying there was no point to it then. She asks the students if they wanted to win and they begin murmuring to each other saying that winning would be nice. Yaya gets mad and tells them that they all had chosen Marimo and Rima says that crowds were always fickle. Saaya says that if anyone was going to do something, there would be no point unless they were number one and that saying the things Seiichiro had just said were excuses for those who knew they wouldn't be number one.
Some people begin to murmur again and Tadase tries to calm them down when they hear a noise. Looking over, they see Marimo had stood up and was looking down. Tadase calls to her and she says that she okay and that someone else should play the piano. She excuses herself and runs off. Amu goes to Tadase and says that she was going to go check up on her. He agrees and Saaya is behind the piano telling Tadase to conduct. He's about to, but she begins to play a different accompaniment and starts singing not so well.
Outside, Amu has caught up to Marimo and tells her that she thought she should play the piano. Marimo looks over her shoulder at Amu and thanks her, but says that she thought someone more skilled should play along to their school's singing students. She runs off and Amu calls after her, telling her to come to the performance and that they were going to wait for her. Ran, Miki, and Su fly over to Amu and notice that she had been crying. Later that day, Seiichiro is walking home and sees that he was on the bridge he and Marimo had been on when she had told him her dream. Amu is at her house in her room thinking over the things Saaya and her group had said and is wondering if they were true; her Guardian Characters disagreeing with everything Saaya had said. She then asks if they thought Marimo would show up to the competition, but they don't answer.
At the 23rd Choral Competition, Amu is frozen solid with fear, but when Tadase calls to her, she comes out of it and he asks if she had seen Marimo because their turn to go was coming up. She tells him she hadn't and Seiichiro hears this.
Marimo is standing in front of a bench elsewhere asking herself if she should go to the Choral Competition. She then remembers some of the things Saaya had said and looks at the ground sadly while her heart's egg gets glazed over with gray before turning into an X-Egg. Amu's Guardians tell her an X-Egg had just been born, so Yaya says they had to go since they were the Guardians. Seiichiro comes up to the four and tells them he was sure Marimo was coming and goes to look for her, Amu and the Guardians following. Seiichiro finds her sitting on a bench and Marimo's X-Egg, which hatched into an X-Character, laughs, making him think he heard something. Her X-Character yells out "forte!" and sends an attack at Seiichiro using its baton, causing him to fly backward and hit the ground, losing his glasses in the process.
Marimo says that she was wrong, and Seiichiro hears her, looking back in her general direction. Yaya runs over and tells Amu she found the Marimo and Seiichiro. Amu sees that her X-Egg already hatched into an X-Character, so tadase tells them they should go stop it, but Amu stops him when she sees Seiichiro pick himself off the ground. He tells Marimo that she wasn't wrong and Yaya thinks he couldn't see the X-Character without his glasses. He goes on saying that she had told him her dream of wanting to play the piano always and a transparent picture of Marimo appears next to her X-Character saying that everyone said there was no point unless you were the best and calls her dream worthless. Seiichiro tells her there was no thing as a worthless dream and she gasps. He tells her that he was the same as her because he wasn't good at a lot of things, but he still had dreams and says that he wanted to become president of a company someday, an astronaut, and a race car driver. Marimo calls him stupid and says there was no point in having dreams like the ones he had and her X-Character fires another attack at him.
Tadase tells Amu that it was becoming dangerous, but Seiichiro is still going, saying that there may have been no point, but that his dreams were all he had to hold onto at the moment. He slowly starts to approach Marimo the best he could because of the X-Character's attack and says that if he began to think his dreams were worthless, he would become pathetic. He says that his dreams were his and his alone and that his dreams were all that mattered, causing the X-Character to stop its attack. Amu steps forward and agrees with Seiichiro. Seiichiro still can't see and calls to Amu who tells him he did a good job before she unlocks her heart and does a Character Transformation with Ran, becoming Amulet Heart. Seiichiro shields his eyes and notices that she was starting to shine in a pink light.
Marimo's X-Character tries another attack, but Amu jumps to dodge and it hits Seiichiro instead, making him fall back again, and Amu apologizes to him. She goes at the character from a different angle and it tries its attack again, but she uses her Pom-poms to block it and ends up right next to it. She tells Marimo's X-Character that she liked her piano playing and then uses Open Heart to purify it. Marimo's Guardian Character appears and thanks Amu and Seiichiro, but he doesn't hear as he was still on the ground looking for his glasses. She goes back to her egg just as Seiichiro finds his glasses and puts them on. Marimo wakes up and wonders what she was doing when Yaya tells her that everything was fine. Tadase steps forward to her and asks if she would play the accompaniment for them. She smiles and gladly accepts. Back at the Choral Competition, just like their practice sessions, Tadase is conducting, Marimo is playing, and the students are singing.
Backstage, some students are congratulating Marimo on a job well done and she thanks them. Seiishiro is looking over at his friend with a smile when Amu comes over to him and says that he had been staring at her for a long time. She then thinks it was because he had "fallen for her" and he blushes, asking her what she was talking about. She compliments him on what he had said earlier and asks why he just didn't confess to her. He blushes harder and tells her no, saying that it was good enough for him to know he could do whatever if he put his mind to it. He says that if he got more confidence that he might confess and Amu looks at him in awe with a slight blush on her face. After they talk, Marimo looks over at him and smiles with a blush and he smiles back, with a blush on his face, too.
- Seiichiro Suzuki: Marimo gets to know Seiichiro after she offers to help him on his singing, as it wasn't the best. She tells him about her dream of playing the piano always, even after she was married, and there he started blushing like crazy, but turns around so she wouldn't see. When her heart's egg became an X-Character, he tells her that she wasn't wrong about her playing and that there was no such thing as a worthless dream when she called hers worthless and he tells her some other things before Amu comes forward to purify the X-Character. Amu even catches on that he might have had a crush on her and tells him to confess, but he said that if he gained some more confidence that he probably would. Though it doesn't seem like it, she may have a little crush on him, too, as she did blush at him with a smile at the ending.
- Amu Hinamori: They didn't really know each other well, but when Marimo leaves practice because of some mean things Saaya said, Amu runs after her and tells her she would be the better person to play the piano. When Marimo's heart's egg became an X-Egg and then a X-Character, Amu tells Marimo's X-Character just before she purified it that she liked her piano playing.
