lore idea

Mumei uses rune to setup a teleport gate to travel through different time and places, kinda tedious but works just fine. And then she got fascinated by the idea of a time machine. So she gets herself a pocket watch and goes to kronii and sana. Enchanted by the power of time and space, it can be used to travel through places and time easily.

One time mumei uses it travel to a place, accidentally bump into young ame. Not knowing her watch dropped, mumei just rush to her destination and ame keeps the watch. Civilization duty got real busy, mumei doesn't have time to find the watch and just go back to using rune gate, eventually forgor about her watch.

ame keeps the watch and waits for mumei's return, but she just never come back. Ame is playing with the watch and got herself teleported. Through trials and errors, ame finds out what the watch can do. She uses the watch to help solving detective cases, and got paid enough for her medic diploma and her live with pets.

One day she walks bubba and mikki, passes a tailor shop and sees a coat that reminds her of mumei. So she got herself a coat, and with the watch, she starts her real detective business.

** fx for using the watch would be in mainly yellow and a string of blue, sana and kronii color, not mumei
