Iyami somehow gets his hands on this concoction thinking he could get famous for his "youthful beauty". A mishap happens and it ends up in Chibita's oden.

    Reina Nakamura is Perfection. Or that's what the world wants you to think. On the outside, she's a beautiful, loving, perfect example of the human race. However, on the inside, she's a touch-starved, insomniac who has the body to back it up. Now residing in Akatsuka, she meets a couple of NEETS and their friends. One NEET finds that he is drawn to her, like a moth to a flame. When Reina accepts him, how will their love develop, and what will the future hold for them both? The series Osomatsu-san and its cast of characters belong to Fujio Akatsuka. All Locations are loosely based on real locations or completely made-up. All other characters are mine. Some pictures are from the anime or from the Internet. Only pictures with 'ChibiRedd1' are drawn by me, but the poses and/or references will be credited on their dedicated page. Warning: Profanity/ Strong Language Cartoonish Violence Sexual Language (Not enough to warrant a mature rating)

    Ichimatsu gets injured and is forced to walk home with Karamatsu. (No BL) (This might be a bit angsty.) Whoop and now another chapter with Choromatsu and Jyushimatsu getting into a bad situation at a concert. This is kinda just practice writing the characters. I might add several chapters simply writing from different perspectives. Warnings will be before each chapter.
