Toda Edogawa (戸田) is Keita's friend, a first-year high school student, and one of the few male characters he interacts with.
Toda appears to be as old as Keita. He has blonde hair and yellow eyes.
Toda is one of Keita's male friends. He is both angry and jealous of Keita's relationship with his sisters and is always one of the first to jump to conclusions about the sexual things that happen in the Suminoe household. He seems to be an average student as he tested into Ako and Riko's high school. Toda is also perverted; the magazine the twins found in Keita's room was his.
Keita - One of the few males Keita is seen to associate with Toda appears to be his best friend. Toda is known to be very jealous of Keita's relationship with his step-sisters as he is hopelessly infatuated with them. It was Toda who convinced Keita to go pray that he do well on his test. Also in the anime Toda gave Keita the porn that his sisters found in exchange for him inviting Ako and Riko to the pool; whereas, in the manga he left it at Keita's house when he went over to study. While he and Keita constantly fight in regards to Keita's love life he is shown to be a true friend to Keita.
- He was named in one of his first appearances in the anime, in the manga his name was revealed in Chapter 18.
- He has a much bigger role in the anime.
- He is hopelessly infatuated with both of Keita's sisters.
- A running gag of the anime is that Riko always punches or kick him away whenever he tries to get close.
