First Encounter

Asuma left the hospital and made his way home. On the way, he encountered two familiar figures. One, Might Guy, was enthusiastically exclaiming, "Let's burn with the power of youth!" while his companion, Kakashi Hatake, looked noticeably embarrassed as people around them began to stare.

Upon reaching home, Asuma was welcomed warmly by his mother, Biwako Sarutobi. She embraced him with motherly love, something he had never experienced in his previous life as an orphan. For the first time, he felt the warmth and comfort of a mother's embrace, filling a void he had never known existed.

Later, Asuma approached his father, Hiruzen Sarutobi, the Third Hokage. "Old man, I need to rest for three weeks to fully recover. Also, I want access to all the jutsu in our clan's scrolls, especially your summoning jutsu."

Hiruzen, with a knowing look, left without answering directly. As he was leaving, he said over his shoulder, "The scrolls will be delivered to you by the ANBU."

Asuma smiled at this. Biwako then headed to the kitchen to prepare his favorite dishes, a gesture that further deepened his newfound appreciation for the familial love he now enjoyed.

With a sense of anticipation, Asuma opened his system and said, "Mirai, open Mirror System."

A blue screen appeared, displaying four characters:

1. Biwako Sarutobi

2. Hiruzen Sarutobi

3. Kakashi Hatake

4. Might Guy

Though he had obtained Escanor's powers, his physical body could only handle 10% of their full capacity. However, he could fully utilize the weapon Rhitta when the sun was at its peak, during noon. To survive on the battlefield, Asuma knew he needed to first master medical ninjutsu, and he chose Biwako as the initial character for the Mirror System.

Before beginning the battle, Asuma analyzed Biwako's character through his enhanced analytical ability:

Name: Biwako Sarutobi 

Title: Jonin 

Chakra Level: Elite Jonin 

Abilities:

- Chakra Control: Max

- Ninjutsu:

 - Three Body Technique

 - Mystical Palm Technique

 - Chakra Scalpel

 - Medical Water Release: Jellyfish

 - Medical Water Release: Water Mosquito

 - Medical Water Release: Water Scorpion

 - Secret Anaesthesia

After reviewing the character panel, Asuma initiated the battle simulation. Despite being a Genin in this new world, he was able to defeat Biwako using just a basic Fireball Technique, thanks to his enhanced abilities. Biwako, while a proficient medical ninja, was overwhelmed by the sheer power and intensity of Asuma's attack. She was known more for her skills in medical ninjutsu and her status as the wife of the Third Hokage than for her combat prowess.

Upon defeating her, he immediately gained the Mystical Palm Technique, marking a 5% completion of Biwako's character in the Mirror System. Asuma continued to engage her in subsequent battles, each time relying on the Fireball Technique to overpower her. Each victory brought him closer to mastering her abilities:

- Chakra Scalpel: 5% completion.

- Medical Water Release: Jellyfish: 5% completion.

- Medical Water Release: Water Mosquito: 5% completion.

- Medical Water Release: Water Scorpion: 5% completion.

- Secret Anaesthesia: 5% completion.

With each encounter, Asuma's mastery of medical ninjutsu grew. He progressively unlocked and mastered Biwako's abilities, culminating in a comprehensive understanding and perfect control over medical ninjutsu. The Mirror System now indicated a 30% completion of Biwako's character. However, the most significant gain was the mastery of *Chakra Control* at the maximum level, allowing him to precisely manipulate and conserve his chakra—a vital asset for any shinobi.

Feeling a sense of accomplishment, Asuma closed the system interface. With his newly acquired knowledge and skills, he was no longer just the Asuma Sarutobi of this world; he was a formidable warrior, equipped with the powers of Escanor and the wisdom of a master healer. His control over chakra was now flawless, and his medical abilities could turn the tide of battle in critical moments.

Asuma looked out the window, watching the sun as it neared its zenith. With each passing day, he grew stronger and more prepared for the challenges ahead. The world of Naruto was a dangerous place, but Asuma Sarutobi, armed with the formidable powers of Escanor and his newly acquired mastery of medical ninjutsu, was ready to face whatever came his way. 

He felt a deep sense of purpose and resolve. The upcoming challenges would be numerous and daunting, but he knew that he had the skills, the knowledge, and the power to overcome them.

With a determined look, he turned away from the window and prepared for the next steps on his journey.
