Onimusha...!

--- Chapter 4 ---

Watase Aoba looked at his partially transformed left arm with a surprised expression.

"Hmm…?" He frowned a little and felt an immense amount of ki suddenly enter his body.

Aoba couldn't do anything except slowly guiding this energy into his meridian, which surprisingly had transformed into something new.

'With this level of the meridian, I can finally cultivate my Ki Arts, but what should I do with this.' Aoba thought about his left arm, which still feels the same even though it already turned wolf-like.

'Let's see..." He closed his eyes and searched for information about this astral soul.

After a few seconds of studying this astral soul, Aoba pondered a little and opened his eyes. 'There is a cultivation art.' He thought.

[Supreme Sky Wolf Art]

[Change Someone's Soul Nature into a Wolf and gained their abilities]

[If someone reaches the pinnacle level of this art, they will able to achieve the strength of the supreme sky wolf]

Aoba's left arm turned into this because of the astral soul, which is the essence of the former supreme sky wolf. If he wanted to control this newfound power, he was obliged to cultivate this art.

'I don't have a problem cultivating this art, but what should I do with my former ki art?' Aoba tilted his head because his previous life's cultivation art literally had a different kind of nature.

"Wait…" He suddenly realized that the supreme sky wolf art is neutral art, so it's not a problem if he cultivates his former heavenly demon technique.

"I can cultivate it at the same time or possibly merge this art with my technique." Aoba's eyes brightened, and his slight movement caused his mother to wake up.

"Aoba!" Shizuka opened her eyes and looked at Aoba.

She immediately hugged his tiny body and shoved her soft bosom into his face. "Are you hurt anywhere? Let me check it." She worriedly said.

Shizuka released him from her hug and checked his body, but then Aoba calmly showed her his left arm, which had transformed.

"Ah, is that your quirk?" Shizuka asked while looking at his white-furred arm.

"Mm." Aoba nodded and slightly learned this supreme sky wolf art, which turned back his arm into normal.

'I only learned the tip of this art, but it's enough to control this partial transformation.' So he thought while looking at his mother, who had a worried expression on her face.

"Don't worry, I'm okay, mom." He said with a smile on his face.

Shizuka released a sigh of relief and sat beside him. "I almost had a heart attack when you fainted a few hours ago." She worriedly said.

"... I'm sorry," Aoba said while lowering his head.

Shizuka shook her head and casually put him on her lap. "As long as you're okay, mom is happy." She said with a gentle smile.

Bam!

The door fiercely opened, and we could see Tomoe stood with a solemn expression on her face. Still, as soon as she saw Aoba, she immediately lunged at him.

"AOBA-CHAN!" Tomoe yelled with teary eyes.

"Okay, stop, right there." Shizuka calmly said while making a water wall in front of herself.

"Guh!" Tomoe hit the wall and felt immense pressure slapping her cheeks.

After that, she comically fell to the floor and released a painful groan.

"Aoba just woke up, don't lunge at him like that." Shizuka sternly said, to which Tomoe responded with a pout.

"So... What actually happened to him?" Tomoe asked while looking at Aoba.

"Let me show you," Aoba said and activated the supreme sky wolf art, which caused his hair to turn white and a pair of wolf ears to grow out of his head.

"K-Kawaii!" Tomoe looked at him and felt such an immense amount of damage just by the sheer cuteness.

Shizuka's eyes also widened because she thought her son Quirk could only transform his left arm into wolf-like, but it seems that she was wrong.

"Aoba already woke up?" Kyojuro and Fuyumi entered the room and then witnessed Aoba in his cute form.

"Grandpa, Grandma?" Aoba said while shifting his gaze to his grandparents.

"This level of cuteness is dangerous." Fuyumi looked at his grandson with a surprised expression.

'This isn't my quirk, though?' Aoba thought while deactivating his transformation.

After a few explanations from Aoba, they released a sigh of relief and decided to return to their home.

"Thanks for the help, Yuuta." Kyojuro gave his student a pat on the shoulder, to which Yuuta responded with a shake of his head.

"I only do what I could do, sensei," Yuuta replied, which caused Kyojuro to laugh a little.

"Then, see you later." Kyojuro and his family walked away to the parking lot, leaving Yuuta alone in the corridor.

--- [Parking Lot] ---

Aoba is about to enter the car, but suddenly a loud cry echoed in the hospital, which caused all of them to frown a little.

Boom!

"An incident or villain's attack?" Kyojuro moved his gaze to the explosion noise direction and frowned.

Boom!

Another explosion occurred, and a few rocks fell to the street, blocking their way out of the parking lot.

"Fuyumi," Kyojuro said while giving his wife a firm nod.

Fuyumi nodded her head and suddenly released some white aura from her body, covering Aoba, Tomoe, and Shizuka.

"Father?" Shizuka looked at Kyojuro with a worried expression, but he calmly smiled and walked to the car's luggage.

Kyojuro cracked his neck a little, and a black aura came out of his body, which formed a black hakama around his body.

"Aoba, Grandpa will show you something amazing." Kyojuro confidently smiled while taking out a black-bladed spear from the car baggage.

"Grandpa knows how to use a spear?" Aoba asked while looking at his grandpa, who naturally entered a stance and pointed his spear forward.

"Well, the Watase family is special..." Fuyumi quietly answered.

"And your grandfather is the last member of his clan before I married him, but sadly Shizuka and Tomoe couldn't inherit his clan's tradition." She continued.

"Tradition?" Aoba looked confused because he didn't know anything, nor did they ever tell him about this.

"Your grandfather is the last Onimusha." Shizuka suddenly stated.

Kyojuro moved forward with significant momentum and slashed his spear to the falling rocks. "Blade Slaughter." He said with a smirk on his face.

The spear flashed like thunder, and the rocks abruptly sliced into half but did not end there. Kyojuro naturally jumped into the air and kicked the falling stones away.

"Hmm, why mother and Tomoe-nee couldn't inherit the family tradition?" Aoba asked, which put a sad expression on their face.

"You see, Shizuka and Tomoe didn't inherit your grandfather's quirk, which is Demon Body." Fuyumi patiently replied while feeling a little bitter. Instead, their daughter inherited her quirk, which was able to control the natural element.

She can control the light element while Shizuka and Tomoe could manipulate the Water and Fire element.

"I see…" Aoba nodded his head and slowly shifted his gaze back to his grandfather.

"Demon Warrior."
