|“||A little bit after I entered high school I, Tomo Aizawa, confessed to someone I liked...||”|
—Tomo Aizawa, Chapter 1
She has short red hair and red eyes. She wears her uniform with the top button undone and she also wears compression shorts (know as 'spats' in Japan) under her skirt.
She is very competitive when it comes to sports, sometimes scaring people by how strong she is. However when it comes to Jun she is very shy and often lashes out when he asks her something as simple as walking home together.
Tomo met Jun ten years prior to the start of the series after he moved from Tokyo, she climbed his fence to greet him. She came back the next day and accidentally broke his handheld game, Jun punched Tomo (believing she was a guy) in retaliation. Tomo tells him to keep punching but Jun is too freaked out by her answer. A few hours later Tomo's father came to Jun's house to apologise for Tomo's actions, even grovelling at his feet. Tomo's mother then comes by and sorts Gorou out. Tomo then asks Jun if he wanted to be friends and he accepts. Sometime later Tomo introduces her childhood friend Misuzu to Jun. She doesn't find what Tomo enjoys fun.
PlotShortly after starting high school Tomo Aizawa confessed to someone she liked, that someone was Junichirou Kubota. He doesn't understand her confession as he thinks of her as a guy. Tomo constantly gets flustered with Jun's minimal understanding of personal space.
Tomo's childhood friend, Tomo has romantic feelings for Jun but he only thinks of her as just one of the guys. Tomo and Jun have neighbours and friends since they were little. Even though they were neighbours they lived in different school districts and that's why they didn't go to grade school together. When they finally entered the same middle school together Jun finally realised that Tomo was a girl, and it was the first time Tomo realised Jun just thought of her as a guy.
Misuzu is also a childhood friend of Tomo's. Misuzu, Jun, and Tomo would all play together as kids. Also their mothers were childhood friends so they grew up together. When they ever got scolded for somethin Misuzu would be elsewhere. With the the addition of Carol to the group, Misuzu and Carol try to help Tomo win over Jun.
Tomo calls Carol 'Cotton Candy' and wants to be as feminine as she is. She is shocked when Carol says that she has married Misaki three times. Tomo and Carol became friends in the first year of high school when Carol went and introduced herself and also asked to be her friend.
Tomo is Misaka's kouhai and they are in the same karate club at school. Tomo is in the boy's karate class because the girls are too scared to train with her. Misaka is a really big fan of Tomo's, it can sometimes be mistaken for a crush though. Tomo (as well as Jun) think that Misaki isn't that strong and have both tried to help him improve.
