It's been revealed that Oomori Seiko and Noko (Shinsei Kamattechan) will be collaborating on another song together.

Noko will participate as the guest vocalist in "Shunkan Saidai me," which will be included in Oomori's self-cover album "PERSONA #1", which drops on July 7. This will be their first time working together since "Hikokuminteki Hero" was released 5 years ago in 2016. 

This announcement was made on May 30 during a live broadcast on YouTube. The two gave a performance of "Hikokuminteki Hero" as well as other songs including Shinsei Kamattechan's "Front Memory." 

The arrangement for "Shunkan Saidai me" is done by Okubo Kaoru, who also arranged "Hikokuminteki Hero." In addition, Pierre Nakano (Ling tosite Sigure) is in charge of the drum performance.
