The Weird Phenomenon

William selected something that could help Angelica fight efficiently. If he selected anything else like movement technique, she'd continue to complain and wouldn't accept such one.

"Ok, I will try this out," she looked a bit satisfied by this technique. She got hyped up and instantly started to train over this technique.

William knew she would need a long time to get adapted to the technique, and yet before he'd move, he felt some sort of a wave coming from her.

He turned around and found a scene he hadn't seen before except for himself. She was standing still, moving her hands around, while muttering the incantation he taught her just now. Around, he could see a shadow that rose up from her body, rising slowly and covering up an area of a few metres around. 

She emitted a dangerous vibe, while the shadow that appeared was vaguely resembling a small version of what she looked like before turning to human form.
