Demon Slayer: The Journey That Began When I Became Yoriichi's Sister

Chapter 639 Self-Destruction

Butterfly tilted her head, her amethyst-like eyes reflecting Yu Zi's confused expression. She chuckled softly, "No, it's just that compared to before, you seem to have begun to face your confusion now."

"Face it squarely?" Yu Zi frowned slightly, looked down at herself, and then spread her hands. "To be honest, I don't even understand where I'm confused or when I started to face it squarely."

She stretched and sat down next to the butterfly, quietly leaning on her shoulder.

The butterfly gently patted her hand and said, "The heart is a magical power that cannot be embodied or understood, but it certainly exists."

"I think you should have a guess by now."

The faint fragrance wafting from the butterflies relaxed Yuko's mind.

Her eyelids drooped slightly, and the events of that night naturally came to mind.

"Do you mean when Yoruichi slapped me?"

The butterfly lowered its head slightly, giving a cryptic reply: "Who knows?"

Yuko fell silent. After a while, she quietly moved away from Butterfly's shoulder, sat up straight, and said, "I think I understand."

"What do you understand?"

Yuko clutched her chest: "Why does the butterfly restrict my regeneration?"

“I can still recall that pain. Even though my memories of previous injuries, no matter how severe or painful, were never this clear.” Yu Zi looked up at the sky along the eaves of the corridor, her eyes seemingly lost in memories. “But the memories of my past lung disease and this knife wound to my chest are exceptionally clear.”

"If my previous lung disease could be explained by the fear of death, then this knife wound can only be explained by the same reason."

The butterfly chuckled softly: "Can't the memories of things happening now be better?"

Yuko's lips curved into a smile as she looked down at her hands: "Isn't this what Butterfly has always wanted me to understand?"

"We should cherish ourselves more and have respect for death."

The butterfly was slightly taken aback.

"I don't know when my fighting style became that I liked to trade blows and defeat the enemy in the most convenient and effective way."

In her usual combat, unless she has the upper hand, Yuko often prefers to fight by exchanging blows, especially against enemies who have an information advantage over her. This fighting style can easily catch the opponent off guard and even end the battle directly.

When she defected from Soul Society, she used this tactic in her battle with Yamamoto Genryusai Shigekuni, and even received positive feedback from it.

“I still don’t think there’s anything wrong with this way of fighting.” Yu Zixu clenched his fingers and turned to look at the butterfly. “If it weren’t for the butterfly’s help, I definitely wouldn’t have understood it.”

The butterfly gazed at her with a smile.

“I cherish myself from the bottom of my heart.” Yuko reached out and hugged the butterfly into her arms.

Butterfly's eyes softened, and she gently placed her hands around Yuko's back.

"The fighting style of exchanging injuries for injuries subconsciously tells me that I won't get hurt, and there's no need to care." Yuko leaned gently on Butterfly's shoulder. "This disregard for one's own life is the real reason you rejected me, isn't it?"

"As expected of Yuko." Butterfly smiled, closed her eyes, and leaned against Yuko's chest. "She understood so quickly~"

"Soon...?" Yuko's lips twitched slightly.

She wondered if butterflies had no concept of time; a hundred years had already passed!

Butterfly gently pushed Yuko away, a smile playing on her lips: "That's right, a person who can't even cherish themselves will only end up with an uncontrollable self-destruction."

"Self-destruction...?" Yuko murmured. "It's a very apt description."

If it weren't for the butterfly and Yoruichi, continuing down this path again and again, perhaps one day she really would have become like that.
