In this crossover anime, I fight against the supernatural in my everyday world.

"What kind of image do I have in your heart...?"

After making that sarcastic remark, the laughter in Yagami Light's voice disappeared, and he spoke seriously.

"I'm calling to tell you something."

"what's up?"

"The famous sword Mikazuki Munechika will soon be on public display at the Tokyo National Museum."

"Oh?"

Upon hearing the name Mikazuki Munechika, Yohoshi couldn't help but become interested.

Mikazuki Munechika, like Onimaru Kunitsuna, is a legendary sword from the Sakura Province.

It is said that this famous sword, which was specially commissioned by the Genji clan to be forged by Sanjo Munechika to showcase the family's prestige, was once owned by the swordsman general Ashikaga Yoshiteru and the unifier of Japan by Toyotomi Hideyoshi. Finally, it was passed down from generation to generation by the Tokugawa family and has been passed down to this day.

Compared to Onimaru Kunitsuna, Mikazuki Munechika, while lacking any fantastical legends of slaying demons, is still a national treasure-level sword.

Light Yagami knew that Yoshinori had once disguised herself as "Mask," invaded the Kyoto City Museum, and taken the famous sword Onimaru Kunitsuna.

Therefore.

Light Yagami then informed Yosei of the news as soon as he learned of it.

"Mikazuki Munechika..."

Ye Xing pondered to himself.

Even without the legend of slaying evil spirits, a famous sword that has been passed down for so many years must have been stained with countless lives.

This malevolent aura alone is enough to make it a powerful weapon against evil spirits.

Just right.

Yotsuya Miko's magical longsword is starting to fall behind the intensity of the current battle.

"It seems it's time for me to go to Tokyo."

Upon hearing Yohoshi's reply, Yagami Light smiled and responded.

"Then I'll wait in Tokyo."

After hanging up the phone, Ye Xing returned to the living room, stood in front of the members of the Superpower Society, coughed twice, and smiled at everyone.

"I just received some news."

"The Tokyo National Museum actually stole our famous sword, Mikazuki Munechika."

"That won't do."

"Perfect timing! Taking advantage of this trip, our Superpower Society must return the famous sword Mikazuki Munechika to its rightful owner."

173 Yukino, who touches the truth, represents the upright positions of the members.

"Returning it to its rightful owner..."

Upon hearing this familiar word, Yotsuya Miko's face showed a look of emotion, and she murmured to herself.

"Thinking back, the last time we did something like this was during spring break. Time flies, it's almost been four months..."

Halfway through her sentence, Yotsuya Miko paused for a moment, then seemed to realize something and said...

"Wait, only four months!?"

Because of her recent experiences, which have been so exciting and fulfilling, Yotsuya Miko feels that the first semester is exceptionally long.

It is no coincidence.

Rio Futaba and the others felt the same way.

But upon closer examination...

It's been less than four months since the last time they stole Onimaru Kunitsuna!

At this frequency.

That's three times a year.

Even if only one item is returned to its rightful owner each time, by the end of a year and a half, all five legendary swords of the Sakura Province will belong to the Chaoliang Company.

By the time they graduate from high school, the top national treasures should all be pretty much finished.

Then, when I graduate from university...

Won't all the museums be emptied out?

Just then, Kawasaki Saki suddenly realized something and exclaimed in shock.

"Wait a minute... Mikazuki Munechika? That legendary sword from the Sakura Province? Returned to its rightful owner? You're going to steal that sword!?"

"Hey."

Ye Xing frowned slightly and emphasized what he had said before.

"How can you call it stealing? Such a powerful spiritual object should rightfully belong to our Superpower Society."

Kawasaki Saki was unaware of the existence of evil spirits and ghosts, as well as the underworld and doors, and didn't understand the logic behind it; she just spoke subconsciously.

"How is that even possible?! That item is kept at the Tokyo National Museum..."

Just as Kawasaki Saki was halfway through her sentence, she noticed the slightly complicated expressions on the faces of Futaba Rio, Yotsuya Miko, and Sakurajima Mai, and couldn't help but wonder.

"Did I say something wrong?"

"Oh right, you haven't seen it yet."

Ye Xing chuckled and said something, then reached out with his right hand, and a long sword hidden in an ancient scabbard slowly appeared in his hand.

Then, he tossed the long sword in his hand, scabbard and all, to Kawasaki Saki, who was sitting on the sofa opposite him.

"This is...?"

Seeing Kawasaki Saki holding the long sword with both hands, looking puzzled, Yohoshi replied nonchalantly.

"This is Onimaru Kunitsuna."

"Eh?"

Kawasaki Saki was stunned for a moment, then looked down at the long sword in her hand.

A few seconds later, her beautiful pale green pupils gradually widened.

"Ghost... ghost... ghost..."

"Why is he stuttering?"

Hearing Yoru's cheerful words, Kawasaki Saki looked up at him, her lips slightly parted.

"you you you..."

"Let's just forget about it."

Ye Xing waved his hand, thinking that if Kawasaki Saki were to utter each word one by one, and even stutter a few times, this internal meeting today would probably never be finished.

"My beloved concubine, I'm entrusting her to you."

Rio Futaba pushed up her glasses, looking slightly helpless and used to Yosei's lazy behavior, and took the initiative to explain to the bewildered Saki Kawasaki.

"Saki, it's like this..."

Rio Futaba meticulously recounts how Yosei and Miko Yotsuya met, along with the events that occurred after the establishment of the Super Scale Society, including the Kyoto Municipal Kindergarten incident, the invasion of the Kyoto City Museum, and the connection between Hina Amano and abnormal weather.

Incidentally, she also introduced the nature of the underworld, the dangers of the "gate" to human life, and the two necessary conditions for awakening the soul's ability to materialize.

After hearing this, Kawasaki Saki's entire worldview was turned upside down, and she was so shocked that she couldn't speak.

If she hadn't witnessed Ye Xing's transformation with her own eyes, she would never have believed that such a thing could exist.

A personified soul? The true form of the soul? The true inner self? An evil spirit capable of influencing people's hearts? Kyoto City on the verge of collapse?

It's incredible.

Just as Kawasaki Saki was sorting out her thoughts and trying to digest everything she had just heard, Onimaru Kunitsuna, who was sitting on her lap, suddenly let out a metallic clang, and the blade automatically drew halfway out of its sheath.

"This is...?"

Seeing that Onimaru Kunitsuna had drawn his sword on his own, Kawasaki Saki's pupils shrank in surprise, and she was at a loss for what to do.

"Did...did I do something wrong?"

Rio Futaba and Miko Yotsuya exchanged a glance, both showing helpless sighs, shaking their heads and chuckling wryly.

"It's trying to please you."

"what?"

Upon hearing this, Kawasaki Saki glanced down at Onimaru Kunitsuna, whose jet-black blade was trembling incessantly. For some reason, a scene suddenly flashed into her mind: a puppy wagging its tail frantically, begging to be petted in order to please someone.

"Forehead..."

Kawasaki Saki carefully reached out and gently placed her hand on Onimaru Kunitsuna's sword.

To her surprise, the legendary sword from the Sakura Province actually responded, rubbing its black blade against her slender, white fingers twice.

really...

It looks like a puppy.

"Almost got it."

Upon hearing his master's words, Onimaru Kunitsuna immediately abandoned his humble demeanor, swiftly sheathed his sword, and returned it automatically to Yoru's hand before disappearing into thin air.

Only then did Kawasaki Saki's expression change, and she covered her lips in shock.

"You actually... gained Onimaru Kunitsuna's approval!?"

Onimaru Kunitsuna, what level of famous sword is that?

Those who have possessed it are all prominent figures in the history of Japan, such as Hojo Tokimasa, the founder of the Kamakura period, and Oda Nobunaga, the sixth "Demon King" who unified Japan...

Let's stop for a bit.

Before Kawasaki Saki could even finish her shock, Yohoshi pulled her out of her thoughts and retorted.

"There's no need for you to be shocked again by something that everyone has already been shocked by; it's just repeating the same thing."
