Hex Haywire, Doppio Dropscythe, Ver Vermillion, Zaion Lanza. All four sound like someone had a stutter and didn't bother to edit the text later. Or thought "imagine how cool it would sound if like a second name has the part that sounds the same as the first name, ikr, it's totes awesome". And gave absolutely no fucks to what the words mean. Also random unsubstantiated rrat - the reason Meloco and Kotoka have normal names and Zaion isn't as fucked is because they were shoehorned much later and Nijisanji was initially planning another male only wave.
