Comprehensive Comic Shura Field Starting from Seraph

My name is Mio, and I'm panicking now because my kawaii sister and older sister met my girlfriend. Krulru: Hey, who is this woman, Onii-chan, and why is she so close to you? Aoi Aki is bragging: Can you explain to me who this woman is, my dear Oudou? , At this time Hiiragi Shinoa said: Well, that dear, actually I, I have it. Wait, I can explain this, Mio said slowly while looking at Kruluru who was exuding black energy and Aoi Aki who was sharpening a hatchet. This novel and its characters are purely fictitious.
