Super weird, but funny

Oyajis and shounen-ai aren't really my thing but the concept sounded so crazy that it just might work.
It's so bizarre and completely unexplained other than "chemical substances" being the cause, but it runs so strongly on gag humor that logic is irrelevant. While I found myself laughing at the ridiculous situations, I also found some moments cute - a strange feeling after seeing a bunch of middle aged men squirming around with blushies smacked across their faces. Can't decide if it's gross or comedy gold.

But what I really, especially liked was that it takes you to a place where (preconceived) sexuality, physical appearances and gender identity are of little importance to who you may find yourself attracted to. While I call these situations absurd, they are. But the attitudes the characters have are a nice change. If we could laugh about these kinds of situations, form close bonds with people we normally wouldn't and not be afraid of judgement then perhaps, in a twisted turn of events, this could be us (but still, I hope not in this particular case... LOL).

This series offers a healthy salad of BL, GL, and het love, so whatever floats your boat you can get here. And if you you only like one or two of those options, it's easy to imagine the others away.

It's about teen girls whose bodies have transformed into older men. They're still girls at heart, so most of them are still attracted to guys...including each other. Even though both parties are girls. Who both look like guys.

The story is really well-told, and overall feels pretty comedic, but with some nice dramatic moments. I also like that it doesn't dwell too much on the usual gender bender stuff, like "Oh wow, so this is what a guy's body is like!" (I read a lot of gender bender, so I've already been over that territory a lot; I like that this cuts right to the story.)

The art is great, and isn't at all like the art for usual BL series, which makes it feel quite refreshing.

OMG! The idea and the story itself is hilarious!
Well Chinatsu's whole entire school turns into a bunch of oyajis due to some pollution problems...The transformation causes her to have some feeling towards her BFF (or just girlfriend) Tomoe xD well Chinatsu's taste is older men.
And then there's the other people who treats the situation like it's not much of a big deal...LOL and eventually humor ensues, you just gotta read it!

Anyways the art is pretty suave~ the guys are pretty handsome and not girly looking at all. This manga is definitely worth the read! and laughs biggrin
