Senoo Akira

Protag’s best friend, which usually means perverted and not liked upon by the opposite sex. Exactly true here. He is another one of those onii-chan that seeks ideal imoutos in eroges…though in his case he’s just not being honest with himself. Although complains his sister’s tyranny to Ryou, he is the first to get angered when his sister is looked down upon. He also hates NTR too.
