Aiko Kudō is another elite student in class A. She is portrayed as a green haired, friendly, easy-going, and mischievous girl. She uses 'boku', commonly used by boys or young men, to address herself. She is extremely skilled in electronic gadgets and carries a micro-recorder for recording lessons, which she also uses to cause mischief to other people by recording, cutting and re-joining parts of their conversations, creating lots of misunderstandings and woes to others, especially towards Akihisa. She especially likes to mess around with Akihisa and Kōta often stating perverted things to arouse them and cause them to nosebleed. It is weakly implied that she likes Kota due to her messing with him at times. Her Shōkanjū is clad in a schoolgirl sailor uniform and wields a battle axe. It carries an accessory that increases the electric strength of her axe.
