Shizune Zenkouji is a neutral character from Valkyrie Drive Siren. A girl from a wealthy family that also has a G cup. Since she was raised as a princess, though she doesn’t realize it, she has quite a haughty attitude. She’s been spotted several times laughing arrogantly like “Ohohoho!” Though she acts haughty, she’s treated more as an eccentric person than anything else. Knowing that Rina has a complex about her small chest, once they became partners, Shizune began attacking her insecurity both mentally and physically. She’s a bit of a sadist.
