This was a great manga, I'm really glad I found it through Warm Milk translator page on Yuurei ni Natta. I hope to read this again in a few years and have the same feelings I do now, 9/10.
But man, all the great authors die young.. RIP Toko Kotoha.
People dying young is not something to laugh your butt off to. If you keep up that personality, pretty soon your social life (if you have any) will be the thing that dies young.
