Chuta Ohsugi

Chuta Ohsugi (大杉 忠太, Ōsugi Chūta) is a character in Kamen Rider Fourze. He is the second year geography teacher and later Gentaro and co. third year homeroom teacher. While at first, he was antagonistic towards Gentaro and his friends, Ohsugi became the first teacher who knows the secret of the Rabbit Hutch and became the Kamen Rider Club's faculty advisor.

Personality
Ohsugi is a middle-aged man with bad looks and a bad personality which makes him unpopular with the students. This does not bother him however, as he believes students and teachers should not be friends. Ohsugi has a habit of punctuating his sentences with a snap of his suspenders. He is in love with Sarina Sonada even though she has no interest in him. He often gets into arguements with Gentaro Kisaragi and his friends over various things such as Gentaro not wearing the school's standard uniform. Ohsugi is also rather superstitious, often reading horoscopes and believing in curses. He likes to put up a strong front, only to shirk and cower later when things go haywire. At first he saw Gentaro as the most troublesome student in the school, including anyone affiliated with him like Ryusei Sakuta who pointed out that the school uniform was not completely mandatory. After finding out about the Kamen Rider Club and that they were the ones behind all the rescues from the Zodiarts, however, Ohsugi gives them his blessing and becomes their advisor. This action even shows another side to him, stating that he wants to become the advisor since, as a teacher, it was his duty to protect and help his students.

An interesting thing to note is that he got used to some of the Zodiarts attacks after a while. During the senior's graduation, he announced that the graduation would continue as planned despite the Zodiarts attack. His response was that it just wasn't uncommon for the school to be attacked on a daily basis.

History
Upon Gentaro transfer to AGHS, Ohsugi immeadiately labeled him as troublesome. Ohsugi would occassionally appear to cause trouble to the Kamen Rider Club whenever they would do something related to the Zodiarts incidents. He would also try to make a move on Ms. Sonada which were often ignored and after she was reported as being absent due to health trouble for extended (when she was really sent to the Dark Nebula by the Virgo Zodiarts) Ohsugi blamed Gentaro and co. for it and became their third year homeroom teacher to make their school life harder for them. But during the Musca Zodiarts incident, Ohsugi learns the truth, and decides to become the faculty advisor for the club.
