In that moment, a horrible chill ran down the back of 15cm Fairy Othinus who had lost her usual spot.

“Touma, Touma! Where are you!?”

She looked in an odd direction as she listened to the white nun continue to shout the boy’s name after he vanished into thin air while partway up the large spiral staircase.

“Aiwass… That name is appearing here?”

“What?” asked Fran who picked Othinus up so she would not be trampled underfoot.

The sole surviving Magic God breathed from her nose.

“Tch!!”

The spiral staircase provided much greater footing. That eliminated the risk of falling, but it also allowed the gear and handcuff rings to become a threat once more as they appeared around Maika. Thanks to that, Tsuchimikado was forced to constantly fight back. The rainbow chain skeleton and transparent flesh and blood could not be defeated without Imagine Breaker, so he was continually beating them back barehanded. Fran seemed to move slowly, but she had joined the fight as the only one who could voluntarily use magic without any risk.

“Aleister had always used the term ‘scientific’ in a positive way. He would say anything, be it spiritual or physical, was scientific as long as it was beautifully ordered and could be explained causally.”

Othinus was a big deal herself for continuing to speak with no change of tone with all this going on.

“And the peak of that theory was Aiwass. That name doesn’t come from anywhere. It doesn’t belong to any religious category. …And this world is formed from the multiple magic side phases that have been placed on top of the physical laws.” She put her hands on her hips and looked to the mountain devilishness. “Aiwass is the angel of the bottommost layer…that is, of the world of pure physical laws. That is why he is Aleister’s greatest treasure. If he establishes a means of controlling Aiwass and uses that tremendous power to destroy all of the filters other than Aiwass, only a magicless world will remain.”

“? ???”

The hoodie bikini girl was part of the magic side, but not even she seemed to understand.

The one who came to a stop was Index.

“Aiwass? But if that appears here while living up to the theoretical values…”

“Yes, this would have been constructed in order to oppose Magic Gods such as myself. That human doesn’t stand a chance of winning in a straight fight.”
