Is Tc immune to electricity because she has lighting powers?
No.

Can Tc be hurt by her own powers?
Yes.

There was a time when Tc sent a shock up each arm, but it ended up exploding out of them.
Quite a painful day that was. Why she did it? Wasn't it to spite Reji for some reason or another?
Things didn't go as planned.

Artist Note: I should have gone over the black area a second time to make the black a solid,
but I don't have the ability to get new Ink pens, so I decided against it. Gotta save on money for a while.
