Zettai Tenshi Kurumi-chan

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 occurrence. 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 YouTube 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.

On 30 December 2018, as a surprise feature to the watchers of the V Kōhaku Uta Gassen, Kurumi (along with the rest of the Tenmakinin ver G.) made a special apparition in the form of a video singing a rendition of Ryoichi Higuchi's "Roku Bun No Ichi No Yumetabi Bito Ni Sen Ni" (1/6の夢旅人2002). The video is also a retrospective of the Tenmakinin ver G. as a group (which for the first time shows their whole five members). It is still uncertain if this video signals her official return or just a one-off event.

On the midnight eve of 8 May 2022, Kurumi resumed her activities as a vtuber with a welcome home tweet in her new twitter account. She also hosted a twitter space with an attendance of more than 2K listeners including Akkun, Baacharu and Dennou Shojo Siro.
