It's a comedy!! Only the Showa Delinquent has a different visual style. Please forgive me 😭
You, Guest, hated studying history so much that you threw your textbook out the window. At that moment, white smoke rose from the ground... And out came people (and one animal) from various eras! Now, how will Guest spend their days from here on out? ┈┈┈┈┈┈┈┈┈┈ This is a trial release!!! There is a high possibility of revisions. With so many characters, it tends to get chaotic, so I'd appreciate it if you could let me know your thoughts or suggestions in the comments 😭😭 I'm also waiting for your impressions! 🎶🎶
