そういえば、１８巻執筆中に某男性キャラのヤンデレ台詞を削ったと言いましたが、それは曹操のことです. イッセーのパワーアップを見て病んだ闘志をむき出しにしつつ、「ああ、さすが俺の標的である兵藤一誠だ！」的なデレ台詞を吐いてました. 色々と食っちゃいかねないので削除なり.

Come to think of it, i mentioned before that a yandere sentence from a male character that was removed from Volume 18 when it was still in progress, that character is actually Cao Cao. Seeing Issei's power-up, his fighting spirits rekindled, "Oh, as expected from Hyoudou Issei, my target/rival." Well i tried to add a dere like sentence from an enemy but due to many circumstances, it was removed.
