With Rokka joining as the (temporary) guitarist of RAISE A SUILEN, the band heads to a film studio to shoot a music video (MV) of their new song. Afterwards, they return to the studio to play their new song, but Rokka struggles to play together with the other band members. After a chat with Masking in a ramen shop, Rokka keeps playing until the song is perfect. The next day, the band is impressed by the PV they put together. During lunchtime, CHU2 inducts Rokka as a permanent member of RAS with the moniker LOCK.
