Word evolution game

[Rounin Ryuuji]

This must be so far into the future I haven't projected what "proper" Imishimé would sound like at this stage, but probably (if I had to guess), like [ɣɐ̞̀.ʑŷᵝːj].

Speaking of which, let's have all these languages reborrow it!

Global shift to inherited words using Tesséki (Hiragana) spellings, and classical reborrowings using Amézéki (Kanji) spellings:

Orthographic reforms: printing is introduced, however the characters are introduced from Late Mediaeval Germany, and the charactersets available are limited based on this (German orthographic tendencies also simply become common):

Revoiutionaries engage in a 30 year long civil war to destroy all established order, which they lose but manage to takeover a few of germanies colonies. As such they begin reforms one of which is to start using vowel letters as consonants and consonant letters as vowels. The people are for some reason okay with this.
