There was actually a typo in the first version of the last chapter they published: when Zenko calls for her brother in the first version, she says:"Bat-oniichan" but later on, Murata published a message on twitter saying :"あ、最新話に誤植がありました. バットお兄ちゃんではなくバッドお兄ちゃんですね. あとで差し替えますすみません！": In fact she says "Baddo-oniichan"...revealing MB's true name. (No, his real name is not Bat (which would have been funny though).So I suppose the brother is Bad and the little sister is "Good" (Zenko can be written with the meaning of "Good thing")

FROM AN CONTRIBUTOR, makes absolutely sense in my opinion, what do you guys think?
