*NOTE: Recommended level is 49.
Obtained: During the Chapter 5 Intermission, you’ll receive a Topic from Barry. After you read the Topic, head to Bloom Palace and speak with Tiki.
After Barry’s little tantrum, travel to Daiba Studio’s Idolasphere. After the cutscene, head to the door on the right that was previously blocked by a barrier. Once in the Back Monitor Room, you should see screens numbered 0 to 9.
The code for the order of rooms you need to go in is as follows: 018769. Start working your way through the rooms until you reach the last room.
Behind the last door lies a boss fight with Greed (level 52) and Hirudineans (level 50). Greed is weak against Axe, Bow and Electric. It resists Fire, Frost, Wind and Red Skull. Sword, Spear and Mind are all neutral against Greed. Defeat Greed then head to the Lessons Studio in Shibuya.
Speak with Mamori outside of the Lessons Studio to trigger a cutscene. Afterwards, the side story will complete. Barry will acquire the Backup Skill “Ninja’s Escape”, which increases our chances of escaping battle. Barry and Mamori also acquire the Duo Art “The Tunnel Home”.
