Well ...
May I have some sort of space distortion type GF?
It's kind of like, upon summoning, it distorts the space and may take cut pieces of the enemy or remove the enemy itself (based on what is taken will determine damage or instant kill)
And a junction ability of spatial storage? That is, he can hide an artillery of robots in a magical space? (Something like, an enhancement for his limit break at much later stages, and also stores other stuff, so like, a spot to actually store those 99 potions you would have in the team type of thing)

Also, time to sleep, so will know what you say/decide when I wake
