What the fuck was Tenmangu's evil plot?

At the end of previous chapter, Misaki began falling to her death.
Now in this chapter, we still se her falling to her death.
But Iwata jumps in after her and throws her into the air so that the others may catch her... before falling to his death himself.
Misaki is pretty much brooding over his demise, and the gang (minus Excel, who stayed with Ill Pala in the previous chapter) makes their escape.
Then they go back to Shiouji's institute of kinky pedo science, and there... they see Iwata who looks olde and/or who lost shitload of weight. Misaki comes up to him, grabs him as if to pummel him to death... and then jumps at him with, what I assume is, deep kiss. They land together on the ground and... then she starts pummeling him to death. Sumiyoshi and Watanabe drag her off him... and she has literally rivers of tears on her face.
She then shuts herself in a room.

Then some stuff happens, and we cut to stache man and Momochi talking about something.
Kabapu falls asleep, Momochi puts a blanket over him... and then fucking Tenmangu Shiouji calls her. Or she calls him. Dunno.
They talk, I think and then, Tenmangu laughs... and then Excel breaks in with a kick and drags Tenmangu out of his room... end of chapter.

Don't tell me that's it? She exorcises Tenmangu, we learn Miwa is dead and umm... TEH EDN? I mean, with that news that Excel Saga is ending soon, does this mean that this is TEH EDN, more or less?
RIKUDOOOOOOOOOOOOOOOO!
I hope he pulls something awesome for the REAL ending, like... Kabapu and Il Palazzo fighting with Eye LAZORZ or something.
He better : P
