Tsuna, who has just turned 20, appears in furisode(long-sleeved kimono). Tsuna-chan is a little tied after being too excited with classmates she hasn't seen in a long time at her coming-of-age ceremony. While she was walking home to watch anime, she was approached by some of her old classmates. The petit reunion is about to begin... ? The alcohol ban has been lifted and the drunken classmates' legs start squirming under the table. A man's foot intrudes upon Tsuna's crotch, which was tightly enclosed by the kimono. The drunken man is even more excited to get closer to Tsuna, who resists with her whisper voice. The man's cock enters Tsuna-chan's crack, which has become so wet that she can't resist! Naturally, the other classmates found out and, in turn, used her as an outlet for the coming-of-age celebrations.
