Slayzer found himself a bit of broken ruin to clamber onto, sitting down upon it and watching as Emma finally got into her first scuffle. He barely reacted at all as she crushed her first opponent, if anything he leaned back on one hand and yawned, cupping his mouth with the other hand before adjusting his position again into a relaxed fashion. Elise held her hand out a moment towards Emma, releasing a gentle wave of energy that surrounded the burnt arm and healed it, it was more effective training if Emma survived through it. However when Emma looked over at him he shifted his spare hand and pointed at his eyes then at the area where the demon had been crushed.

Mana was floating in the air, not an uncommon phenomena when a demon died, normally it was generated in a number of ways, physical activity and training for starters, learning and focusing the mind helped to control it, but the energy of a defeated opponent remained in the air and was typically drawn towards the victor, an attracting force drew it towards Emma and began to fill her with little bits of energy,
"Lesson 2, naturally you will draw in mana from opponents. You have, in a sense, two mana pools, an exhaustive amount that you actively use in day to day activity or combat and a greater capacity besides it which you tap into when you need to perform large, powerful tasks-"
"-or to use unique abilities like Confining!" Penny interjected, a little more confidently, Slayzer glanced at Penny then smirked and leaned back again, "Confining existing demons and recreating them is one thing, but you can actually create new demons, you have the power to create new living beings. Usually you can only create something weak, the strength of an average human, but they can get stronger too. Many demons were created this way."

Slayzer stared at the rest of the demons they'd recruited for training and sighed,
"So are you pansies gonna do this one at a time or show a little guts and attack in groups? We don't have time to waste on your hesitating." He questioned, a couple of them gave him a few indignant stares before starting to pair and group up. The one that had been crushed a moment ago beginning to reappear, courtesy of Elise' healing powers,
"Healers use a magic similar to confining but not quite the same, they can recreate the fallen and restore life to them for a fee. People once considered them necromancers but necromancy is actually a pretty dead art." Penny paused for a moment, considering what she'd said before bursting out into a fit of giggles.
