My sign-in system

Surya moved on to the Spider demon after defeating the first two. He's not sure if they're small spiders like in anime. Surya jumped from tree to tree, eventually reaching the house suspended in the air by threads.

Surya glanced at the monster suspended on the spider thread. When it saw him, it swiftly hid inside the home. The spider may have already felt his power.

"Infinite breathing: Third form—silent wind."

Surya destroyed the demon and looked for more little demons, but there were none. Surya moved slowly approaching the main house. He spotted Rui standing at the house, holding his sister's head. He can probably predict what happened. Maybe she decided to abandon Rui and escaped.

"You were the one who killed my family."

"I'll kill you."

Rui wrapped multiple multi-layer threads around Surya, but Surya just cut them off. Rui was in astonishment. In the past, he had never experienced somebody cutting threads like that. Rui made the decision to get serious.

"Blood Demon Art: Cutting Thread Rotation."

Surya glanced as the threads approaching him, cutting everything in their path like vegetables.

"Infinite breathing, Second Form...Endless Fire."

A fire was started around the Surya, instantly evaporating all threads. Surya's sword turns crimson, like magma. Rui also sensed danger. He experienced a scorching sensation across his entire body. Surya chopped off Rui's head easily by strolling.

Surya's second form relies on fire breathing. It simply generated a tremendous quantity of heat around the user through means of breathing. Surya's sword will become crimson like magma. This technique also affects the target, causing it to feel scorching. After slicing the demon's head, the entire body will be consumed by fire.

"You....killed.... a lower...rank...moon...demon."

"I'll notify HQ..."

"Wait...for...the...summon..."

After seeing the lower moon demon dead, the crow spoke a few words before flying to headquarters. Surya knew that by killing the Lower Moon demon, he could become Hashira, and the demon he killed was about fifty. The kakushi group will clean up the aftermath.

Some people failed the Final Selection exam but became Kakushi to continue serving the Demon Slayer Corps. The majority of them give first aid to demon slayers on the battlefield and clean up after fights.

Surya began to slowly descend the mountain while checking the system's notifications. He had approximately fifty low-level sign-ins and one medium-level sign. In every low-level sign-in, he received attributes and bombs. He received ten space rings after signing in at the mid-level. Each one measures approximately ten cubic meters.

After killing demons, his regeneration talent grew by one point, and he gained new poison resistance abilities. Importantly, he obtained Spider thread talent by killing demons. All of this is due to extraction talent.

*********************************

Infinite castle.

Muzan was outraged when he realized Rui had died. Muzan liked Rui since he, like him, suffered a deadly illness when he was human. All of the demons share information through cells, and Muzan has access to all of their memories.

He also witnessed Surya slaying Rui with a bright red sword. After witnessing the sword, Muzan became a little terrified. Once again, forgotten memories resurfaced. After witnessing it again, He affirmed that the swordsmanship style was different, but Muzan become wary of Surya. Muzan understands the dangers of the bright red blade. He instantly shared all of the details with the other demons.

"Find and kill him. "Those who bring his head will be rewarded with my blood."

After getting news from the Muzan, all of them went active. Getting Muzan blood allows them to grow stronger and maybe they challenge the upper or lower moon. All demons began searching for Surya.

****************************

After two days, Surya received a response from the headquarters via Crow. He was now Hashira, and he had been requested to meet with the head at headquarters. The bird directed him to the headquarters. On the way, he encountered an unexpected person. It's Mitsuri Kanroji. Surya was surprised to see her. Surya saw her going dejectedly down the road and decided to walk beside her.

'What should I do? My marriage has been called off.'

'Will I ever marry off?'

'How do I tell my parents?'

'Why was I born with this strength?'

While Mitsuri was contemplating, she heard a male voice.

"Hello, are there any inns nearby?"

"Ahh...."

Mitsuri abruptly regained consciousness and stared at Surya beside her. She was fascinated by his handsome looks.

"There is...""I'll take you there."

'Mitsuri, what are you thinking and why are you talking to a stranger?'

'Strange....why am... I... acting... this.... but his face is charming.'

"Your face looked really bad just a second ago. "Has anything happened?"

"That...my engagement was called off."

'Mitsuri, why are you telling him this?

"What...your engagement has been called off."

"Which idiot did that? "You are incredibly gorgeous."

"It was called off because of my hair.

"Your hair is beautiful... it looks like Cherry Blossom flower petals"

"I really like that color."

"Don't worry about the color of your hair. It's quite attractive, and didn't you notice my hair color."

Mitsuri felt happy after hearing his words and looked at his hair color. When she initially saw him, she just noticed his face; but, after seeing his hair, her face reddened, and her heartbeat quickened. She was also surprised his hair color.

"Everyone likes my hair color."

"Really."

"Yes, it is true. So don't worry about your hair color."

They walked to the front of the inn without realizing it.

"You stated that your marriage had been canceled. What about me as your marriage partner?"

Mitsuri's face grew extremely hot, and she nearly collapsed. She felt her hand being touched and looked at Surya, who had touched his hand. She noticed something in his palm and heard what he was saying.

"This is a meeting gift—a good luck charm that will ward off evil."

"You never told me your name. My name is Surya Dev."

"I'm Mitsuri Kanroji...."

"Mitsuri Kanroji....what a lovely name.... I am waiting for your...reply..."

"That..." Mitsuri ran away from him, embarrassed. Surya smiled as he stared at Mitsuri's back.

How does he not take the main female character of the anime into his pocket after meeting her? Surya played small tricks on the Mitsuri. Mitsuri will have ideas about him. Surya didn't control her mind, but he certainly influenced it.
