Mira stayed in her soul for a bit longer than usual, destroying the monster repeatedly, trying to think of a better plan that won't make her endure so much pain. She looked around and detected hundreds of holes in her soul caused by the tentacles.
'If it keeps going like this, I really will die, losing my body and soul to this disgusting creature.' Mira thought, but there wasn't much she could do. The creature was immortal, after all. No matter what she did or how many pieces she cut it into, the monster always reformed to its original appearance.
'Or is it really invincible?'
Mira's eyes sharpened, and she raised her hand toward the monster. A clump of darkness soon appeared, spinning at such high speeds that it didn't look like it was moving. All the light in her soul soon got absorbed by the black ball, increasing its power.
After a second, Mira nodded and tossed the black hole, which she called a Singularity Strike, at the monster.
