he can beat pretty much any monster, spirit, or magic glass demon thingy...but girls (and gynoids) nope, he just gets pushed around, punished, and used. if the the phrase or whatever the hell they are really want to win, they just need to separate him from his girls and send a girl shaped phrase to destroy him, getting him alone would be the hard part, but once he is, it'd take like 5 seconds and he's dead, then they can easily fulfill whatever their purpose is, so long as it doesn't turn out to be searching for him (cause I could just see the ironic twist being that god made his body out of the master phrase thing they are looking for which in turn is why he has basically unlimited mana and can use all types of magic)
