SHIKISAI (シキサイ)'s lineup has changed:

Bassist taka has seceded on September 10th. The band tweeted that his reason for leaving is due to his mother falling ill and asking him to withdraw in order to not potentially contract Corona Virus. The band decided that because of this, it would best if they continued with 3 members and use a support bassist until taka can be replaced.
