for those who want it here is the spoiler,
I believe Oka makes his entrance but it really is not very clear and i believe this is on purpose. It should be even more difficult in the scan to make out i think, but it looks like a major component of the shape of his suit/mech/whatever you want to call it, is a large gantz shaped sphere type object. Interesting isnt it?
any nerd boy's suit is out and the boss is sprouting arms. Kato show up only to be surrounded by the army whilst he klings to nerd boy. I like Kato but he is a sap.
the other two bosses land next kato and nerdo crushing many members of the army at the end of the chapter.
most important thing i drew from this is that oka is watching but failed to swoop in and kill nuri so he obviously does not have kyo's know how for points analysis as he could have easily got 100 points in the last chapter but didn't.
