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.
"This is bad..." William knew how troublesome her eroding power was. And when he got worried about the other two, the shadow stopped growing, and seemed to cease expanding.
Yet he didn't like such results. He thought back to how he had such an unexplained phenomenon. "Something must be common between me and her," he muttered to himself, while an idea flashed in his mind.
He didn't train for a long time, and now he felt the urge to start training right now. For a reason, he felt like doing so next to her would be a good idea, one that could help him understand why his training was this bizarre.
He took a glimpse over the other two, making sure they were away for enough distance. The two were training diligently, deeply immersed in what he taught them, and weren't aware of anything happening around.
"I hope nothing bad will happen," William took a deep breath, sat on the ground, crossed his legs, and started to train.
Usually when he trained, he'd lose any connection with the outside world, even time would run and feel differently. And yet this time it was different.
"Do you have an explanation for any of that?" She resisted the urge to speak for a few minutes, yet William didn't say a word. He kept moving around, looking at the weird shadow that got from the merge.
"So far I know nothing," he paused, turning towards her before patting on her head as if he was a father patting on his daughter's, "but it's for our own good."
"How so?!" she got irritated from getting treated like this, hurriedly pushing his hands away from her head while pouting her lips in complaint, "I can't train right now!"
"Indeed you can, indeed you are," William raised an eyebrow before adding, "just treat this like a special form of training."
"Can humans train like that? Amazing!" like any little girl, she jumped fast from being irritated and returned to her old curious self.
"Treat it like this," William truly got nothing to say to explain any of this, however he decided to go along with this solution she provided to put an end to this useless discussion.
"Cool!" As he expected, she forgot everything about what happened, got distracted like always with anything related to humans that monsters never had, "can I dance then while training? Can I sing? Can I drink? Can I sleep?"
Yet unlike what he expected, what seemed to be the best way out of all this turned to be a new source of trouble for him. She kept jumping around, asking such weird questions non-stop, making his eyebrows twitch uncontrollably for a few minutes.
"How about this, can you teach me another technique and let's see if I can train with it as well?" just before he'd explode on her face to shut her up, she suddenly said such words that froze him in place.
"How come I never thought of this before?!!" against what she thought, he slapped his forehead, as if he was regretting something, "sure, let's try this out... How about a..."
"I want to learn something cool, something explosive, something deadly!" without waiting for him to finish his words, she excitedly shouted, making him inwardly sigh.
