When a modern soul named Lin Mo awakens in despair, he discovers he has been transformed into Rengoku Hishin, the young adopted son of the Rengoku family, and finds himself in the world of Demon Slayer, where man-eating demons run rampant. Fate has bestowed upon him cruel trials, but also a unique gift: deep within his soul is the unbroken legacy of the legendary swordsman Kenshin Himura's "Hiten Miken-ryu" (Hiten Miken-ryu), along with a profound memory of the tragedy of the original story.

Holding the legacy in hand, yet burdened with regret, Fei Xin vowed: Never let those warm lights go out again! He combined the essence of Hiten Miken-ryu's "super speed" with the breathing techniques of the Demon Slayer Corps, forging his own path on the brink of life and death—**Fri no Breathing**! The crimson blade blazed like a meteor, piercing the darkness, imbued with the swiftness of thunder and the scorching heat of fire, and bearing the conviction to protect and not kill.

Starting from the arduous training in Narrow Mist Mountain, Fei Xin used the red blade in his hand to slash towards his predetermined tragic fate.

Thousands of years have passed, and the Invisible Empire has returned. But before them stand three insurmountable mountains. ——The invincible numerical monster, the super hybrid, the "All-Killing" Captain of the Thirteenth Division, Ichigo Kurosaki. ——The Touching and Inspirational Emperor, the Lord of the Soul King Palace, the "Dream Collapse" God King Aizen Sosuke. ——The veteran time traveler, the System's favorite son, the "Fighting God" Second Generation Captain Shinomiya Takashi. ...

【Lonely Rock】+【GBC】+【Mygo】……

Gravity vortex, band, easy daily life, distortion, love.

Qian Yu came to a music world where he was unfamiliar with the place and started a new life in Tokyo of this world. Relying on his talent, he inexplicably got acquainted with a group of girls in a band.

The thorny child Jing Qinrencai and the gravity penguin girl Gao Songdeng; the drunkard Besluo Rupa, the scumbag Besliang beggar; the vain Saint Aine, the archangel Hongxia of Shimokitazawa; the divorced rich lady Su Shi, the lying entertainer mom 486; the adorable Xiaozhi, the silly Xiaomu...

The girls in the band are so friendly, and the relaxed and comfortable band atmosphere is something you can't find anywhere else.

However, in the dark house, the first friend he met, Hachiman Kailing, looked at him coldly, enjoying his embarrassment: If you like playing in a band so much, then play with me for the rest of your life. Don't hate me, you asked for it.

Qian Yu: You are here to save me, right?

Liang: I got to base first, you have to pay to play.

Qian Yu fell into deep thought.
