[Sutibaru]

Came from (TS物)(成年コミック) [森山塔] キはキノコのキ.

Here is a pretty fun TG comic that I downloaded. A few sequences.
Even if they are fairly short.

Basically from what I can tell, the boy makes a potion from a mushroom to give his crush. He ends up eating it himself and becomes a chick.
This happens a few times through the manga.

But I like the art. Gives the good 80's feel that I love in manga.
