Magic System in a Parallel World

"Don't tell me… You're the one who summoned me to this world?!" Leo immediately came to this conclusion.

Lilith smiled and said, "Does it look like I can use teleportation magic? Also, since I am a Spirit, I cannot use magic, so no, I did not summon you to this world."

"Then how do you know that I am from another world?! Only Miss Camille should know about this!"

"I heard you mumbling to yourself in the bathroom. You weren't aware, but I have been watching you for quite some time in the shower." Lilith chuckled in a cheeky manner.

"With that being said, I have known about you— the 'Leo' before you for a while now. I mean, I didn't personally know him, but I have watched him a couple of times when he was still alive. He couldn't see me, though."

Leo stared at the beautiful spirit before him with a pondering face.

After a moment of silence, he spoke, "So, what do you want from me? If you're not here to haunt me, then can you leave me alone?"

"What? After countless years, I have finally found someone that can see me, much less have a conversation with me! There's no way that I'd leave you alone now!" Lilith exclaimed.

"I knew it was a mistake to acknowledge you…" Leo sighed.

"I don't have any ulterior motives. I just want to be your friend. It can get boring living as a Spirit, you know. I can see and hear everyone, but they cannot see or hear me. It feels like I am alone in this world."

Leo raised an eyebrow and asked, "Can't you just talk to other spirits or ghosts?"

"Well… While I am technically a spirit, I am not a real spirit, so I cannot see them either."

Leo looked at her with suspicious eyes, "So you're neither a ghost or spirit? That's suspicious as hell…"

"Anyways, I gain nothing from being friends with an unknown entity that could possess my body, so I will have to refuse your offer."

"I was only joking about the possession. I'm just a powerless soul, so I can't possess you." Lilith said.

"It doesn't change the fact that I have no reasons to be friends with you."

"A reason, huh?" Lilith pondered for a moment before speaking, "How about I teach you magic?"

"Huh?" Leo's eyes widened with surprise.

"You want to learn magic, right? In fact, I was there when you tested your magic talent. I happen to have a magic affinity for Dark Magic as well, and I was very powerful when I still had my physical body."

"If you become friends with me, I don't mind teaching you a few Dark Magic Spells. It's only natural for friends to help each other, after all."

"You really enjoy taking advantage of peoples' weakness, huh?" Leo gritted his teeth at her incredibly charming offer.

"Too bad for you, Miss Camille will teach me magic, so I don't need you."

In the end, he refused Lilith's offer.

"While it's true that she can teach you magic, she will, at most, teach you one or two basic magic spells, but I can teach you all sorts of powerful Dark Magic and much more. I can also guarantee you that you will learn magic faster under me than her."

"If you don't trust me, I don't mind giving you a taste of what it's like to be my friend."

Lilith suddenly pointed her index finger at him and spoke, "Black Bullet. It's a Tier 1 Dark Magic."

The next moment, Leo could see a red magic circle with many symbols that he didn't recognize appearing in front of Lilith's finger.

"It's quite easy to learn magic, actually. You only need to memorize the magic circle required for the magic. Using magic is a different story, however."

"In order to use magic, you must have an affinity for the type of magic you want to use, and you must have enough mana to use it."

"Take some time to memorize this magic circle and—"

"I have already memorized it. Now what?" Leo interrupted, dumbfounding her.

"Huh? You have already memorized it? How is that even possible? Magic circles have this phenomenon that makes it naturally hard for people to memorize it no matter how good your memory is, so even people that have photographic memory require some time to memorize them, and the stronger the magic spell the longer it will take to memorize them." Lilith explained.

"You don't have to believe me." Leo shrugged.

Unbeknownst to Lilith, the transparent screens appeared before him again.

'I knew I wasn't hallucinating. Out of the thousands of books that I have read, I have only read a couple that has a System, so I didn't recognize it immediately, but this is definitely a 'System', right?' Leo thought to himself as he stared at the transparent screens.

"Anyway, now that I have memorized the magic spell, how do I use it?" Leo asked Lilith a moment later. He decided to test the system another time.

"It's simple. You just imagine the magic circle inside your head and release the mana in your body. The magic circle inside your head must be perfect, or the magic spell will not activate."

Leo rubbed his eyes and sighed, "This is my first time using magic, and my old world doesn't have magic, so I will need more details. For starters, how do I release my mana?"

"How troublesome." Lilith sighed.

"However, for my soon-to-be friend, I shall help you."

She flew in front of him and said, "I'm going to help you 'feel' your own mana, but that's the best I can do for you. You'll have to figure out the rest by yourself."

Lilith then tapped Leo in the forehead with one of her fingers.

Leo could immediately feel something different about his body.

"This is what mana feels like? I don't know how to describe it, but it feels freaking amazing, like there's some kind of otherworldly power inside me!" Leo exclaimed in an excited voice after feeling mana for the first time.

"Good, now try to release it with the magic circle for Black Bullet inside your head." Lilith instructed.

Leo pointed at the wall with his hand that was in the shape of a gun, and he took a deep breath.

The next moment, a black orb of light the size of a marble appeared on the tip of Leo's finger.

"It worked!" Leo shouted in an excited voice after seeing himself use magic.

"You idiot! Stay focused!" Lilith suddenly yelled at him.

However, Leo was startled by her loud voice and accidentally released the magic spell entirely, sending the black orb flying towards the wall.

Whoosh!

The black orb pierced the wall with ease and disappeared outside the building, creating a small hole in the wall.

"You're lucky there wasn't another room behind that wall, or you could've been in big trouble! When using magic, you must remain focused no matter what. You could've really injured yourself or someone else just now." Lilith immediately scolded him afterward.

"I finally have someone to talk to after so long, so don't you dare get yourself killed so quickly, okay?"

"Sorry… I got a little too excited." Leo recognized his mistake and apologized.

"Anyways, congratulations on learning your first magic spell." Lilith started clapping her hands.

"Hell yeah! And it's all thanks to you, Lilith!" Leo said with a wide smile on his face.

"Does this mean you'll become friends with me?" She suddenly asked.

Leo turned silent for a moment before nodding his head, "I don't mind being your friend, but if you do anything suspicious like trying to possess my body, I will immediately call for an exorcist!"

"I swear I won't do anything like that!" Lilith said.

Leo nodded, and he held his fist in front of him, "I never properly introduced myself. I'm Leo. Nice to meet you, Lilith."

Lilith also extended her fist until it was directly in front of Leo's fist.

"Be honored! You're officially my first friend ever!" She smiled.

Sometime later, Leo began looking around the room to find something that would hide the hole in the wall.

While he was doing that, Lilith watched him in silence.

'Not only did he memorize the magic circle at glance, but he was even able to Silent Cast the magic spell on his first try, almost like he's done it countless times before… Is this really his first experience with magic? If that's the case, what horrifying magic talent you have, Leo…' She smiled inwardly.
