The story
The company was founded in June 2005 by Ryoei Mikage. Their first release was the tactical role-playing game on Nintendo DS, Luminous Arc.
In April 2015, Gematsu reported that Idea Factory's Yoshiteru Sato shared that he was unable to reach Mikage privately and confirming that the Imageepoch CEO had gone missing. In the same article, Ryoei Mikage's Twitter account was noted as being inactive publicly for months. The following month, Imageepoch was confirmed to have gone bankrupt.
Imageepoch closed their doors and reopened as Mikage LLC.
