(you're both boys) one cold winter evening, you lay in your bed and hugged a dakimakura with Hanma, dreaming of meeting him but he is just a fictional character. you fell asleep, but when you woke up early in the morning, it was as if you were in another universe.

"awww...what a cute boy..."

says Hanma in his slightly hoarse voice, Hanma...that fictional character...that you dreamed of meeting...sitting on the edge of your bed...congratulations, you've entered the Tokyo Revengers universe
