I Can Transmigrate into the World of Anime

'Finally! I can upgrade my breathing style to the 'basic' level with the demon Point.' Ryou thought and looked at the lucky draw he got, slightly excited.

He got the Nature Breathing style from the lucky draw. If he gets another skill on par with his breathing style, his strength will soar.

But, Ryou's excitement doused when he saw the rewards present in the lucky draw wheel.

[1. Sun Breathing Style] [2. No Reward] [3. Tekkai] [4. No Reward] [5. Soru] [6. No Reward] [7. Observation Haki] [8. Transparent World]

Out of eight options, there are three 'No rewards' while the other rewards aren't that luxurious except Observation Haki.

"System, what's the meaning of this? Why's the lucky draw different from last time?"

"Host, the First Lucky Draw you get after transmigration is special while the other Lucky draws are ordinary ones." The system replied in a mechanical voice with no emotion.

"Fine! Spin the lucky draw!" Ryou spoke, grinding his teeth.

After spinning for a few seconds, the lucky wheel stopped at number 3 'Tekkai'. Since he had no expectations, Ryou felt better when he got a skill.

Something is better than nothing! After his approval, the system transmitted the reward to his mind of how to practice Tekkai.

Tekkai hardens the user's muscles to the level of iron. Not just defense, but it also enhances one's attack significantly. In One Piece, some Tekkai masters were able to fight on par with Armament Haki users.

'It's a useful skill! With Tekkai, I don't need to fear demons easily injuring my body.' Ryou mused.

At the same time, he knows Tekkai is directly related to his physical strength, so to maximize the benefit of Tekkai, he needs to train and improve his physique.

Ryou then used the Demon Point and upgraded his Nature Breathing to the 'Basic' level from 'Unranked'.

[~ Name: Ryou

Race: Ordinary Human

Skill: Nature Breathing - Basic [0/10]

Demon Points: 0 ~]

As soon as his Nature Breathing reached the Basic level, he felt as if he practiced the breathing style countless times.

His breathing pattern was enhanced while some of the forms that he couldn't execute properly became clear to him.

At that moment, the system's voice sounded in his mind. "New Task is released. Host, please check the details in the Task Bar."

[~ Task: Obtain the rare ore: Rainbow-colored crystal

Details: The ore can be found in Aoshima - Located approximately 650 kilometers away.

Reward: A sword that can Slay Demons [System made] ~]

Looking at the task, Ryou was puzzled since the system gave him a task to find an ore but also mentioned its location. 'Is there any difficulty in this?'

When he asked, the system replied. "Host, the mentioned location is located underwater. It won't be easy to obtain it if you don't master the concept of — Total Concentration Breathing: Constant."

"I see. In the end, everything comes to strength." Ryou sighed and raced back to his home.

It was Morning when Ryou reached home.

When Uncle Daishi saw his return, he exclaimed while his worrying expression eased. "Thank god. You returned safely."

"Uncle Daishi, I told you I would return safely." Ryou shrugged but seeing Daishi worried for him warmed his heart.

"So, did you kill the demon?" Uncle Daishi asked.

"Yes," Ryou replied and recounted his experience of how he killed the Demon.

"Good. Ryou, you should join the Demon Slayer Corps. They know about the demons more than you do. With their help, you would be safe even if you encounter a demon." Daishi advised.

"I know, Uncle Daishi. I will join after some time." Ryou replied.

After resting for a day, Ryou left the house after saying goodbye to Uncle Daishi. He plans to travel to the location mentioned by the system to complete his task.

At the same time, Ubuyashiki Mansion,

Kagaya Ubuyashiki looked at the report and smiled. He had light skin, black shoulder-length hair, and a curse mark that covered his left eye region.

Unlike in the series, the curse mark hasn't completely spread on his face. He looked elegant and simple with a slight smile on his face.

"A masked man who isn't from Demon Slayer corps killed a demon with ease. But, he didn't want to join the corps. Interesting man!" Kagaya spoke gently.

"Master, do you want him to join the Demon Slayer Corps? I can go in person..." Gyōmei Himejima, the Stone Hashira who was present in the mansion asked.

"No need. All the paths with the same goal lead to the same destination. Tell Hashiras about this person, if they meet by coincidence, they can invite him to the Demon Slayer Corps." Kagaya spoke.

"Yes,"

After a week of traveling, Ryou finally reached the place mentioned by the system; there he saw a steep seacliff that abuts the blue ocean.

Appreciating the beauty of the place, he explored the area. He soon found a barren mountain peak along the coastline that stood out from the lush mountain region.

With a quick sprint, he reached the top of the barren mountain where he saw a beautiful lake which is unusually deep blue in color. Since he was looking from above, he could tell the lake was deep and clear with no to little sediments.

"System, are you sure there's no danger inside?" Ryou asked as he could tell it was a volcanic mountain from the traces.

"Host, don't worry. The lake formed naturally after a volcano collapsed following an eruption. The water comes mostly from rainfall and snow.

The system issued this task to test your breathing technique and the pressure your human body can endure. Not to kill you mindlessly." The system emotionlessly replied.

"I see" Ryou uttered, took off his clothes, and directly dived into the lake.
