So, Akira's plan is to overwhelm the eye singularity's ability to teleport attacks? That seems like kind of a risky bet because in principle the eye singularity shouldn't need to affect the attack itself, per se, he just translocates it. So, one could assume that no matter how many joules of energy the attack has, it's all teleported on the other side of the eye singularity, to continue on its merry way up to the planetary orbit and beyond, or perhaps the attack has a ballistic trajectory and will destroy a random castle 400km away, making Megumin proud.
