He's a fair-skinned boy with presumably light blonde hair. He's only been shown in his school uniform throughout the manga.
He acts like a cheerful, affectionate, and very trustworthy boy and he pretended to care a lot about his ex-girlfriend, Tsurara Takahashi, but, when pornographic photos of Tsurara were exposed, he accused Tsurara of being a cheating slut. Tsurara tried to convince him otherwise, but he harshly kicked her, causing her to get a nosebleed.
- His name Akai translates to "Red".
- After Tsurara committed suicide, it is not clear what has become of him. Perhaps like Melissa Maina Mitsushiro, all responsibilities could be pushed to classmates and accused.
- Many students have witnessed the scene where he abuses Tsurara's face and abuses, and if he is regarded as the perpetrator who forced Tsurara to commit suicide, it is judged that the cause of her suicide is due to a shock of broken heart. It may be done.
