[[folder:Main Characters]]

!! Ryōta Sakamoto
->'''Voiced by:''' Kanata Hongo (Japanese), Tyler Galindo (English)
* AboveTheInfluence: When he defeats Himiko with her own stun gun, he's aroused by how good she smells and is barely able to resist temptation... not without giving us a PantyShot first, of course. In the manga, he goes a bit further by lifting her skirt and actually [[WhatTheHellHero touching her on the crotch]] before pulling her skirt back down and reprimanding himself.
** [[spoiler: In the final episode, he kisses Himiko and it seems things are going to go a lot further between them. Even though she lays down on the couch and is not actively resisting him, he knows her UsefulNotes/{{Consent}} is very dubious, and this time he solidly refrains from doing anything further.]]
