the concert scene has ridiculously detailed mobs. It's almost jarring in relation to drawing level of the rest of the episode. I think it might be something Nobuyuki Takeuchi would do?
HARELUYA II BOY #03 has a partial studio giants outsource. Takeshi Ito's part here? He often drew wide cheek bone shading like at 0:19 and again at 0:36. It's probably the most respect Takahiro Kishida's designs had on the show.
