1. Amano comes to the rescue (unlikely).
2. De Mountain joins Kenzou's team (something like this would fit nicely to Out's formula, judging by the last page).
3. Iguchi actually motherfuckingly comes to the rescue (my personal favorite, but we say this every cliff-hanger, lol).
Also, yeah, Kenzou is OP, and keeping in mind that Iguchi managed to beat him one-on-one is virtually giving me chills, but I'm a sucker for him in this series.
Also as always thanks for your hard work, delivering a whole volume at blazing speed second time in a row.
