Zettai Tenshi Kurumi-chan

Zettai Tenshi Kurumi-chan(ぜったい天使くるみちゃん,lit. Kurumi the absolute angel) was a Female Japanese Virtual YouTuber

Introduction Video
This video was deleted, as were all her other videos.

4chan's /jp/ board has archived offline copies of all her videos, other than her last YouTube upload, which was online only for a few hours, in a public MEGA folder that gets posted in the Virtual YouTuber threads on that board. The archive additionally contains an a copy of all her Tweets, songs posted on her mqube and videos posted on her blog.

Personality
Kurumi was an angel with red, fire-like hair who wore a black sailor suit.

When she uploaded the first video, she used a 2D avatar with FaceRig, later she made an original 3D avatar.

She usually spoke in a relaxing voice, but she became more active when playing games or singing.

Sometimes she broadcasted "surprise concerts" and sung powerfully, her singing voice received high praise.

She got along well with the professional YouTubers who debuted around that time.

”Sakayake tenshi to doutei daimao”(酒焼け天使と童貞大魔王; an Angel whose throat is burned by alcohol and virgin demon) was a duo of Kurumi and Akkun-Daimao.

They, VT-212(Neets), and Inui Shinichiro also made a team of Virtual YouTubers, "Ten Ma Ki Nin"(天魔機忍; Angel, Demon, Machine, Ninja).

The February 14th incident


On Valentine's day 2018, Kurumi has a short exchange with Akkun Daimaou, where she ends up throwing chocolate at him. Shortly after all her account names are changed to "sorry for having been shit" in Japanese and her avatar is changed. A short time later her Twitter account and YouTube accounts are deleted. Her Steam and TwitCasting accounts remain.

Among others, Mirai Akari notices the deletion and notifies Akkun Daimaou. At this time most people believe Kurumi's accounts have been hacked. After some time Akkun Daimaou tweets that he has managed to contact Kurumi and finally relays a message from her :

"I think there are many who were surprised by the sudden occurence. Straight to the point, the situation is that all my accounts have been taken over and deleted. Myself, I'm in a state of confusion and don't really know what to do, but for now, I'd like you all and the lambs not to worry about me and keep enjoying the virtual youtubers' contents! If I return, at that time I hope for your support once again. To the Tenmakinin who collaborated with me, to the lambs who got involved with me and the virtual youtubers: Thank you so much. It was really fun! Until the day we meet again. See you!!!!!!"

At this point, the common assumption is that her accounts have been hijacked or hacked. People post on 5ch, noticing Kurumi's other account (Steam, TwitCasting) and shortly after those posts the corresponding accounts are deleted too.

Meanwhile, in /jp/'s virtual youtuber threads, an archive of her videos is created, missing only the last video  she uploaded, which was only available for a short time and which, according to witness reports, was about about her playing Eighth Note.

Roughly 31 hours after her first accounts are deleted, her Twitter account goes back online. The handle is soon changed to @hcsrathts and the name to kkk. Some people were speculating that this was Kurumi recovering her accounts, but kkk used a tool for "dark history" purging to delete all tweets in Kurumi's account.

Shortly afterwards, kkk tweets that Kurumi will cease her activities due to family reasons, insults her, claiming she had neglected her family, and demands that her fans should verbally abuse her should she ever return. After a short time the account is deleted again and a new, locked account is created with the original account's handle, likely to prevent her from creating a new account.

Akkun Daimaou later confirms that he had previously heard Kurumi's family with his own ears on some occasion and that he no longer has any means of contacting her. After discussing matters with the other members of the Tenmakinin ver. G group (excluding Kurumi, including Gorilla), he announces that they will hope for Kurumi's return.

Trivia

 * Almost all of her videos and covers are still available in archives thanks to her fans


 * There were two occasions - one March 23rd? 2018 in VRChat, and a April 24th 2018 Akkun Birthday livestream in Kaiji's channel that was attended by a massive number of VYs - that an account with Kurumi's name and/or what sounded like her voice briefly appeared, and even sang during the latter occasion.
