Devil's Destruction - Devilgram
"You're cute when..."
Belphie starts playing but is as unsuccessful as Beel and Mammon. Mammon suggests looking up tips online but Belphie, determined and angry because of the failures, refuses as he wants to beat the game on his own and starts insulting Mammon for the suggestion. Beel joins it too, so Mammon has enough and goes to sleep. When Mammon's sleeping, Beel prepares an analysis of enemy patterns in the game to help Belphie pass. Later, Mammon wakes up to the twins using him as a pillow and notices that they finished the game. He's very proud of them completing the game and decides to let them sleep but as he shifts, he knocks the controller out of Belphie's hand, waking him up and resetting the game. Belphie blows up and starts insulting Mammon again as he wanted to take a picture of the ending screen as a trophy.
