He is concerned about how aggressive Shion can be at times and needs to pull her out of a simulation she uses to test KOS-MOS. Allen wants to ask Shion out on a date, a fact that is known to his coworkers, but is too nervous to do so. When the gnosis attack the Woglinde, he is rescued along with the other Vector employees by KOS-MOS, and the two then go and catch up with Shion. Allen is able to flee on the escape pod with Shion and the two are eventually found by the Elsa. Shion threatens to kill both herself and Allen if KOS-MOS doesn't cease her desire for the Elsa to leave them there to be picked up by someone else. After boarding the Elsa Allen befriends the crewmembers. He reports back into headquarters along with Shion and is dismayed when he realizes no one noticed he was missing. Allen remains on the Elsa along with Shion and assists her throughout the remainder of the game.
