Huh... Morioh... Part 4 had -imo- next to [spoiler of part 7]Valentine[/spoiler] the best main villain, but also pacing issues. Lot's of unnecessary characters and arcs, truly a "show of stands", more than a story, which I personally found to be repetitive. Also, I wasn't a fan of Hirose, he embodies a lot of what I hate in fiction ([Small guy whose "real problem" is his self-confidence], [Ugly lazy "Nice Guy" that gets a girl falling uncontrollably in love with him], [Despite being mentally weak, gets an incredibly powerful ability], or in short - self-insert-thrash), so I hope he's not a returning character.
I'm very excited to see what this part will bring.
