Summary[]
At the same time Okarun concludes that the diorama is actually a board game, Momo tries climbing up the tilted wall in front of her but fails as she slides down, much to her frustration. Momo then finds herself under attack by a giant knight that suddenly burst through a wall and realizes that her powers can't be brought out in the game. As the giant knight swings his giant sword towards Momo, a mysterious player with a similar appear to Okarun's Turbo Granny form comes in to save her and defeat the giant knight using umbrellas. The player then asks Momo who she is and why she is in the game. Momo answers that she is looking for Unji Zuma, which turns out to be the player as he undoes his transformation and identifies himself as Unji.
