“Virgo. Heh, Heh, Vau, Yod. Guide the light of the 6th Sign that has already been lost due to precession, oh angel with an 8-letter divine name. Drive out the approaching calamity!!”

Yellowish-green light grew from her fingertips.

But before Kamijou could figure out what that meant, the bicycle gear chain moved forward. And just as the head gear turned…

“No! Wait!!”

Index shouted out and the light from the rabbit-ear antennae girl’s fingertips went haywire.

It first seemed to change to a bright red and then it exploded in her hands.

“Uuuh!?”

The girl groaned at her own explosion and the handcuff chain approached next.

[...]

“…Why did Aries, the 1st Sign, activate…?”

“They’re working in our heart to change the color scheme we picture in our head! The handcuff is stagnation and the gear is acceleration. From red to purple, the colors of light separated by the glass pillar are being flipped around!!”

A high school boy like Kamijou had no way of judging how dangerous this was, but it seemed to make people lose control of their magic.
