Due to the changing of times from print to electronic news, ORE Journal fell out of business. Daisuke spent the last few years wallowing in sadness, not having moved on. When Sougo approached him to ask about ORE Journal, Daisuke bluntly said he wasn't it's editor-in-chief anymore.

Later after Shinji returned and encouraged to look forward once again, Daisuke was happily able to accept the role as editor-in-chief once again.
