The announcement came suddenly yesterday evening, Maniac Local Time:

[お知らせ]
皆様に重要なお知らせがあります。こちらをご覧ください。「潮賽乃吉脱退」https://t.co/qvYk38Rgl2

— ゆくえしれずつれづれ (@yukuetsurezure) April 16, 2016

The announcement includes a message from Kichi herself; it seems that she has a thyroid condition and has basically already graduated; their live last week/end was her last with them. For context, she hasn’t been on Twitter in a week, and that’s basically impossible for an idol to do unless something’s seriously wrong.

Kichi will get to be a legend in a way, though, as her short stint in Yukueshirezutsurezure left us with the “Shinjuku Cinema” single and the upcoming Antino Ideology mini-album, and pretty much everything that we’ve heard from that is bowel-voidingly spectactular.

Sayonara, Kichi.
