Bleach: Replacing Byakuya, I Grow Stronger by Beating Ichigo!

I already have 150,000 words written ahead. Three days before the novel goes on sale, I'll release all 150,000 words at once.

I accidentally transmigrated into the world of Bleach and took over Byakuya Kuchiki's body. But Ichigo Kurosaki has already become a Soul Reaper, and the story is about to reach the part where Byakuya goes to the World of the Living to capture Rukia. What am I supposed to do when I haven't inherited Byakuya Kuchiki's combat experience?

Wouldn't it be embarrassing if I went there and couldn't beat Ichigo Kurosaki, who's still wearing his white outfit? Answer quickly, this is urgent!

Ichigo Kurosaki: "I don't know why, but Byakuya Kuchiki is always just a little stronger than me. He keeps coming after me to fight and beat me up. I can't think of anything I've done to make him hold a grudge."

Kenpachi Zaraki: "Kuchiki, come fight me! Today, I'm going to beat you!"

Aizen: "How is this possible? I've evolved so many times, so how can Byakuya Kuchiki defeat me in one hit?"

Yhwach: "I proposed the Five Special War Powers, but Byakuya Kuchiki has already surpassed them. He is my lifelong nemesis!"
