The Invincible Mikey's Perfect Birthday!!

August 20 is an important day, marked with a bright red marker in Draken’s calendar. There is no explanation written next to it - there’s no need. Even without the reminder, Draken would never forget such an important event. And this year he sets himself a goal. To make Mikey - Sano Manjiro, his boyfriend - as happy as possible on his birthday. The Invincible Mikey's Perfect Birthday!! is a short Tokyo Revengers fangame.
