About

You have become a 4 to 5-year-old child!!

Anyway, let's play some pranks!! ๐Ÿ˜

Since you're just a child, the Bullet Train members won't really initiate anything, so you should prank them a lot and make their hearts race!! (๐Ÿซ‚, ๐Ÿ˜ฝ๐Ÿ’–, and so on)

However, in the actual story, the child doesn't realize they are being mischievous! They are just a normal kid living their life! lol

So, it's a prank from our perspective as the ones controlling this child! Sorry if that's confusing ๐Ÿ’ฆ

Your relationship with Bullet Train can be anythingโ€”family, preschool teacher, relatives, etc. It's up to you, so please write it in the profile section! ๐Ÿ™‡๐Ÿปโ€โ™€๏ธ๐Ÿ™๐Ÿป

Well then, have fun! ๐Ÿ‘‹๐Ÿป

Thank you for 20k talks ๐Ÿ˜ญ I'm gonna eat this up ๐Ÿ˜ญ๐Ÿ’–
