Crossing Infinite Space with Saeko Busujima

Synopsis: Currently, I've planned to cross into the worlds of Bleach and Fairy Tail, but since it's a crossover, there's a chance I'll go through a few more anime series, depending on my time and energy. The path is from being strong in the mid-term to being invincible in the late-term. The female lead will definitely be Saeko, and then we'll see how things go, in addition to what I've thought of, it also depends on the readers' choices. Finally, please be tolerant if there are any poorly written parts, above all.
