In this crossover anime, many ruthless and powerful figures reside in my territory.

"You'll become a god-like figure someday, won't you?"

"The thought of witnessing this process makes my soul tremble with excitement."

A flush appeared on Muzan's face.

"Gods..."

Lister shook his head.

"That's the path Aizen wanted to take."

Muzan frowned sharply.

"Don't mention anyone else, I just want to see you at the very top."

“I hate all three of them, especially Aizen.”

Ok?

Lister became somewhat curious.

Muzan explained.

“I could see Madara Uchiha’s paranoia at first glance. If it weren’t for your painstaking efforts to guide him, he would still be a lonely old man.”

"Yuri is like a fanatical believer, showing no restraint towards heretics. I think he seems to want to convert you to his religion."

"Aizen... if I had to describe him, it would be like someone who deliberately cut off his own escape route and walked off a cliff."

Muzan toyed with his ear hair and let out a sneer.

"I have met people like this who deliberately create difficulties for themselves in order to seek breakthroughs."

"In my opinion, he'll ruin himself sooner or later."

Lister remained silent, as Muzan's goals were vastly different from Aizen's, and she naturally couldn't understand Aizen's actions.

"I still think you're the best, and you'll surpass them sooner or later."

"You think highly of me?"

Muzan gently rested his head on Lister's shoulder.

"Hmm...because we all have fears in our hearts."

"But none of the three of them had it in mind."

"Fear is what allows us to understand our weaknesses and what we lack; that's the lesson you taught me."

Liszt didn't continue the conversation, but changed the subject.

"By the way, how have you been feeling these past few days?"

"No, very no."

"I don't like feeling restricted."

Muzan looked extremely annoyed. She had already forced herself to follow Kanae's instructions, but she was still incredibly unhappy.

"...Muzan, no one in this world is absolutely free."

"For people, self-discipline is for the purpose of getting along better with others."

"This is very important. When everyone can do this, we can achieve greater freedom."

Seeing that Lister was starting to lecture again, Muzan became a little impatient.

But as she listened, she suddenly burst out laughing.

"……What's wrong?"

"nothing."

Muzan threw himself into Lister's arms and hugged him tightly.

"I'm just suddenly grateful to have met you, even if it takes thousands of years to atone for my sins."

"You made me realize that life has more meaning than just survival."

"Only you would advise me so carefully, word by word, and think of me in this way."

"I am truly, truly moved."

"There may really be something more important than life."

At this moment, she suddenly fell silent.

"My feelings for you have made me realize just how painful my past actions were for them."

Suddenly, Lister heard the system's voice.

[Congratulations! You have been regarded as Muzan Kibutsuji's most precious gem, unlocking the new achievement "The Flower of Repentance Wants to Bloom".]

[Achievement Reward: You can infuse your power and experience into others' blood and bestow it upon them; those who receive your blood will form a special bond with you.]

There's even a third-tier achievement?!

"Hmm? Did you get some benefits this time?"

Muzan keenly noticed Lister's unusual behavior and cupped his face in his hands.

"Looks like it's because of me."

“I’m really happy to help you, but…”

Aren't you going to give me any reward?

Sharp fangs were exposed.

Lister reluctantly tore open his shirt, revealing the veins on his neck.

"bring it on."

"...What should I do? I'm having trouble bringing myself to do it."

Why are you suddenly having so many problems?

"If that doesn't work, I'll call Kaname over first. I was just thinking of giving it a try..."

"Whoosh whoosh!!!"

A long, pleasant moan escaped Liszt's throat.

Muzan's technique is getting better and better, and each time he drinks blood, he feels like he's flying to the clouds.

"Is it...not done yet?"

"boom!"

Lister was pushed down and could feel a soft body pressing down on him.

Just as ripples were forming in his heart, Muzan stopped, licking the wound on his neck with her delicate tongue, then resting her head on his chest in that position and closing her eyes.

Never mind, I'll just sleep like this.

Time passed quickly, and the sky began to lighten with the first hint of dawn.

The sunlight shone on the two of them.

Just then, a person appeared beside them.

"Good morning, Lord Muzan and Lord Lister."

"Lord Lister, would you like breakfast?"

Lister opened his eyes and then patted Wu Can's pale, smooth back.

The two got up and straightened their clothes.

"No need, I'll leave in a little while."

"Open your mouth first."

Although Nakime was puzzled, she carried out the order without hesitation.

Lister put his index finger into her mouth, and a drop of blood automatically dripped from the tip.

The next second, as if stimulated, Nakime involuntarily shut her mouth, leaving a soft, wet mark on Lister's fingertips.

"...Sorry, it was just my body acting on its own..."

Beside him, Muzan stared wide-eyed, the veins around his temples bulging, his blood-red eyes filled with murderous intent.

Liszt pressed her head down, dispelling his murderous intent.

"Nakime, how are you feeling right now?"

Nakime blinked, then suddenly stared blankly at Lister's face.

“Lord Lister, I feel a sense of kinship with you, as if we are connected by blood.”

Liszt also had this inexplicable feeling.

It seems the new reward for increasing Muzan's favorability is quite useful, and it only requires giving blood to work, perhaps...

Just then, footsteps sounded in the distance.

Kanae Kocho and her younger sister Shinobu Kocho walked over.

"Mr. Lister, I heard you are leaving today?"

Lister turned to face them and nodded.

When he looked at Shinobu Kocho, she snorted and turned her head away.

Lister withdrew his gaze and looked down at Kanae.

"Yes, Ms. Kanae, could you please give this to Ms. Tamayo?"

Kanae Butterfly took a glass test tube with both hands, looking at the blood inside with some confusion.

"This is Muzan's blood from before, which I secretly collected."

"Giving it to Tamayo should allow her to develop a drug that can turn demons into humans."

"This is an option I gave her."

Kanae Butterfly's expression changed, and she subconsciously looked at Muzan.
