Astraia*

astraia* (アストレイア*) is an "absolutely orthodox" idol group with a pure and innocent concept. They were formed in May 2018.

All members except Tsutsui Kana were set to graduate in April 2020 with the group going on indefinite hiatus to find a new lineup, but it was later decided that Tsutsui would graduate as well. Social media for the group has been removed, and whether they will return is currently unknown.
