In 2016, ADELTA achieved broader recognition with the release of their second game, Hashihime of the Old Book Town,[2] the title gained strong attention for its surreal writing and distinctive artstyle.

Following Hashihime, ADELTA would later release UuultraC, in 2020.[10][11] Around the same period, ADELTA established another dōjin circle mainly focused on producing audio works for all ages called ADELTA:M.[12] In 2021, ADELTA announced its next major title, Ooe, via its official blog.[13] In 2024, ADELTA released a trial version of the game, which then later followed up with the complete edition of the game, in 2025.[3]
