I like that this silly ecchi manga puts so much weight to every new antagonist character it introduces. Being Garaku, Mei, Hinojiki, Boy Matsuri... they all remain as important, colorful side characters. With boy Matsuri I wonder... will it be the same, and we'll have two Matsuris until the end (Suzu harem) or will they combine somewhere down the line? In this chapter it becomes clear that boy Matsuri won't simply disappear or get exorcised. I hope they stay separate and learn to live together knowing full well their condition. Many ecchi shenanigans will ensue. How hilarious will it be if they somehow become "aware" of each other.
Also, yeah, I too LOL at Suzu's cervix reaction at boy Matsuri's request. What a riot she is; brilliant character.
