Ha ha ha! I have NOT seen the entire chapter, but I've seen two images from it. When Hotaru gets to where Natsume is (in the relay) he has this, "get away you freak-of-nature" look on him (check it out). As for the cosplayers...

Jinno-sensei: Hard Gay (Oh my gosh...)

Tono: Pirate (with something stuck to him)

Yamanouchi: rabbit

Misaki Harada: sexy girl (Tsubasa can't stop starring ><)

Their race after they've been clothed takes place during the first half of the chapter. The third half of the race, where Tsubasa, Ruka, and Natsume are racing, takes place afterwards. Natsume and Tsubasa seem to battle each other through this race. When Tsubasa gets ahead, Natsume catches up and gets ahead. Once they get to the last challenge, they have to bring the animal in the box to the goal. Natsume ended up with Pyo (the huge chick that won't move), Tsubasa got a speedy monkey that he can't catch (reminds me of Sumire's speed ball), and Kitsuneme gets Mr. Bear (run before he kills you). Sakurano gets a pigpig.

Because Ruka's team player got the worse of cosplay (a mountain), he ended up starting very late. He uses an eagle to try and catch up, but he ends up falling and hurting his ankle. But that doesn't stop him, for he still runs and catches up to them all. He chooses a box and ends up getting a mad Robot horse and it kicks him! Of course, he ends up calming the situation and wins the race. Yeeeeeey Ruka!

As for that b***ch Little Luna,  she appears at the very end, warning Natsume that their "fun" and "building of happy memories"...won't be for long. NATSUME, WHAT'RE YOU GONNA DO, MAN???!!!!
