Okuma was a loner because of his father being the lewd perverted type to be a lewd terrorist like Ayame (AKA Blue Snow) and being in a Place where lewdness is strictly outside the law, it lead him to feeling alone, but not for long.
He was going to reunite with his childhood crush Anna Nishikinomiya and join schools. But ever since the first kiss accident in episode three, he thinks Anna is mad at him for doing something considered "lewd". But turns out when trying to find out who his stalker is, he sees how crazy Anna actually was and gets raped, leaving him no more feelings for Anna, after seeing her sexual crazy side.
He is a part of Ayame's schemes for bringing lewdness back into the world of Shimoneta. He doubts everything at first, (even when he got raped by his ex-crush) he then sees how a world without lewdness is a cruel world, because just like Anna, the people there can't differ between love and lust and end up wanting to rape the person they want romantically.
He is also a son of a notorious terrorist named Zenjuro, who was arrested years ago after trying to spread condoms around the Diet building in defiance of the moral laws. According to his fellow classmates and peers, Tanukichi graduated from a public middle school with the "lowest morals score".
Ayame is the Vice-President of the Student Council and co-founding member of SOX, Blue Snow. Initially, Okuma was blackmailed by Ayame into helping her cause, or she'd frame him and have him arrested. While Akuma was extremely hesitant, he resigned himself to aiding her cause only to avoid getting in trouble. However, Okuma soon warmed up to Ayame and became an official member of her cause, choosing to follow in his father's footsteps.
He also seems to have a crush on her, but is also a bit weirded out by her Blue Snow persona.
Anna is the president of the Student Council and Okuma's his childhood friend. Initially, Okuma enrolled at her school in an attempt to get close to her stating that he was in love with Anna due to her innocent and pure personality, and wanted to follow in her footsteps to earn her to win her affections.
Okuma was extremely reluctant to join Ayame's side, as he knew it would put him and Anna's relationship on thin ice, but decided to continue his life as a terrorist, believing that letting Anna know would be more harmful.
While he does care about her, Okuma is disturbed by the perverted and yandere side of Anna's personality.
