BLOOD disbands

A brief USA tour is held
USA tour ends at the Anime USA convention
Sponsored event and part 1 of the last live with the current lineup is held.
Sponsored event and part 2 of the last live with the current lineup is held. A DVD is freely distributed to those who attended both days.
The wording of the event description (" 現メンバーラスト主催イベント" {current members' last sponsored event}) implies that there were plans to return with a new lineup. However, as of 2023 this has not happened, meaning that the band effectively (but not technically) disbanded.
Vocalist Hayato secedes.
BLOOD unofficially pauses activity
Looks like their last event was " 現メンバーラスト主催イベント": their last live with that current lineup, implying there will eventually be a new lineup, so not technically disbandment.
They are effectively disbanded but I'll update the bio to reflect the correct terminology.
