According to the band's official biography, their first and second drummers died soon after joining. Allegedly, after the death of their second drummer, the band began using a picture of the first drummer's skull in their promotional material as a “warning.” Still, a third drummer did eventually join, who also allegedly died soon after.

These claims are probably(?) lore crafted by the band, rather than fact.

For example, the drummers' names UNI and IKURA are unusual as they can can also mean “sea urchin” and “salmon roe,” respectively. It's also unlikely that the members would have access to a clean photo of another person's skull, or that they would be able to use it without controversy. Additionally, if someone had died on stage at Urawa (浦和) Narciss (as the band claims of their second drummer), there would likely be news stories about it. Details are unconfirmed either way.

According to bassist shan (香-shan-), the band changed from a session to a “practice project” at this time (despite their new name literally containing the word “session”), with a plan to later change their name again and start full-scale activities as an official band.
