u/Bloodchild-

I discovered this universe thanks to the anime, and I've fallen in love with the magic system.

I personally find that despite its simplicity it has a lot of potential, and a few addition things could make the possibility explode. Like 3D spell in the form of a sphere.

After the last episode I've been thinking about what I would have done, and I probably would have used this in the same situation.

I snooped around a bit on the wiki for how the sign and sigil work, but I didn't go farther in the story.

Hints:

1. >!The center sigil is my custom try to make the inverse effect of one!<
2. >!The spell is and offensive one, but it can be used without hurting the target or the surrounding (normally)!<
3. >!The top corner spell is to shoot the main spell and anchor it somewhere!<

So try to guess its effects use the hints or not.
