Are we ever going to find out whether "W" child means "Waste/worthless/witch" or what? Also the story doesn't make sense, but the bro team up between Mikito (clone) and Mikito (Wakaba) makes it worth it. It's just a weird fucking premise and it's funny to me.
It feels like the story is rushing to its conclusion since Wakaba just magically can fight now merely from being in the hyperbolic brain chamber offpage.
