Reincarnated as a Failed Villain: Fallen Angel

"Here." Lilith and Sarah walked into the study and sat on empty chairs. "What's going on?"

Lilith saw the surprised look on Lucas's face and her eyes widened in shock. 'Did father told him the truth?' Lilith's hands started trembling, so she put them in her pockets to hide it from everyone else.

Sarah noticed Lilith's shaking hand immediately and she whispered at her. "What's wrong?"

Lilith shook her head quickly. "Nothing." She lied.

"Girls, could you help Lucas learn magic?" Isaac asked.

Isaac leaned closer to Lucas's ear and whispered, "You can pretend that I unblocked your mana." Isaac knew that entire facade about Lucas not having magic was for Sarah.

Lucas smiled and nodded. "Thank you. Lucas muttered quietly, making Isaac smile.

Sarah kept looking around in disbelief, "Is this true?! Lucas can use magic now?!"

"Yes. Would you like to teach him?"

"I don't know... I don't think I am good enough to teach someone..." Sarah nervously scratched her neck. "T-That's something that teachers should do..."

"Oh, please. I will help you!" Isaac laughed and stood up. "Let's start the lesson right now."

Lucas awkwardly looked between Isaac and Sarah.

After some time, they began the lesson. Isaac explained to Lucas basic concepts of human magic. Stuff like casting spells, activating them, and using them.

"You see... for magic spells, practicing your visualization is a key factor. It must be clear in your mind what you want to do. Then, you must focus your mana on a specific location. In other words, you must visualize the spell in your mind, then activate it by focusing your mana on that location." Isaac explained.

Lucas nodded. 'Just like it was explained in the ... Speaking of which, I forgot to ask who wrote it.' Lucas thought to himself.

"Like this?" Sarah created an energy ball on her palm.

"Well... Yes." Isaac awkwardly scratched his forehead. "This part of lecture is for Lucas, who never had actual magic studies." Isaac muttered. 'I mean, he knows how to force his mana out of his body, but he never actually learned how to control magic.' Isaac thought to himself. 'I'm too lenient with him...'

"Then..." Lucas wasn't nervous. He created a black energy ball on top of his palm, just like Sarah. "Now I activate it..."

"I-It worked! I can't believe it! Lucas is such a fast learner!" Sarah exclaimed happily.

"No... No, Lucas... You're forcing your mana out of your body, not focusing it on a specific location." Isaac corrected. "If you continue like this, you'll just hurt yourself." He noticed that Lucas's skin began to peel off. "See?"

Lucas looked at his palm, and quickly hid it from Sarah and Lilith with his sleeve. He felt pain in his palm. 'Damn. I thought I was hurting myself because my mana was too powerful for my body!' Lucas thought to himself. He was a little disappointed that it was because he was using his mana incorrectly.

Lilith seemed interested in the lesson as well, she created a powerful energy ball that was circulating her golden mana. She was able to create multiple balls at the same time.

"So... Let's practice, shall we?" Isaac suggested. He gazed at Lucas and added. "Just be more careful."

Lucas nodded and focused his mana towards his palm. He tried to imagine a small sphere of darkness floating above his hand, he started to release his mana slowly without forcing it through his skin like he used to. Instead, he visualized the energy sphere hovering above his hand. He continued until he had a small amount of mana inside the sphere, then he activated it. The energy ball floated on top of his palm, and he carefully moved it in midair, however, he accidentally dropped it.

As soon as the ball touched the floor, it exploded violently. A shower of black dust covered the entire room.

"Ngh... I-I'm sorry. I got carried away..." Lucas coughed, coughing up some of the black dust. "W-Wait... SARAH, LILITH?!" He anxiously looked around the room to see if Lilith and Sarah were okay. Luckily, Lilith created a barrier around herself and Sarah.

"T-Thank you, Lilith..." Lucas muttered.

"Don't worry, Lucas." Lilith smiled, patting him on the shoulder.

"A-Are you two alright?" Lucas asked.

"We're fine..." Lilith replied with a little smirk on her face. "How about you? Are you okay? Did you hurt yourself?"

"Y-Yeah... I'm alright." Lucas answered, he looked around to see that Isaac's clothes were burnt. "S-Sorry..."

Isaac sighed, "It's fine. Just try not to play around."

"O-Okay." Lucas mumbled, embarrassed.

Meanwhile Sarah was staring at Lucas in awe. She could barely believe how powerful Lucas's mana was despite seeing it with her own eyes.

"L-Lucas... That was amazing!" Sarah exclaimed, amazed by how much power he had. "You can use such a high level of mana! It looks so easy for you... Even I couldn't do anything like that!"

"I... Uh... Thanks!" Lucas awkwardly replied.

"Is this the power that mister Isaac awakened in you?!" Sarah asked with a look of amazement. "Could he improve my magical power as well?!"

"H-He might be able to do that..." Lilith mumbled, unsure of whether or not he should tell her. 'Does she really need that tho? For a human she is already on heroic level' she thought to himself.

"It's not like I increased his magic power," Isaac lied. "It's his own, I just released it." he tried fixing the situation, without having to actually create another monster. After all, deities can give humans insane amount of magical power, but that usually corrupts them.

'Woah, Lilith's father is top-tier liar!' Lucas thought as he stared at Isaac.

"Ah, s-so you just... woke up his magic potential?" Sarah's eyes widened in shock.

'I could have done it... If his mana was actually sealed.' Isaac scratched his head awkwardly as he thought to himself.

"Y-Yeah." Isaac noticed Lucas's gaze and decided to change the subject so he wouldn't have to continue lying. "Anyway. Let's continue with magical lessons, shall we?"

"Alright." Lucas, Lilith and Sarah said and nodded.

"Wait, you don't need magical lessons." Lucas gazed at Lilith.

Lilith simply showed him her tongue.
