Kaiser never expected to wake up in a place like this—a vast, endless library filled with books that weren’t just stories, but entire worlds. Chosen as the Librarian of the Fantasy Library, his job isn’t to read these books—it’s to live them.
With the Authority of Ultimate Control over All Weapons, Kaiser isn’t just a visitor in these worlds; he’s a force to be reckoned with. His journey starts in The Asterisk War, where he claims the legendary Orga Lux—Ser-Veresta and Gravisheath. But things only get crazier from there. In High School DxD, he gets his hands on True Longinus, the strongest Sacred Gear.
From dueling in Asterisk to battling devils, clashing with Soul Reapers in Bleach, and facing gods in Campione, Kaiser is about to carve his legend across the multiverse.
After all, if reality doesn’t live up to expectations—he’ll rewrite it himself.

Author! Could you tell me how many chapters are left to finish the work, please? Could you also tell me if Yuri or ntr is in the story, please?
A Sincere review. ===== Writing quality: top-tier. no complaints at all. [5.0] ===== Update consistency: also solid. there's a justifiable gap between posts, but when a new chapter drops, it’s usually several at once. and honestly, i'm loving that release pace. [5.0] ===== Story development: amazing. the author takes their time building each world properly—doesn’t drag out useless scenes or skip over everything either. scenes hit just the right length, and each world ends with a proper, satisfying conclusion. honestly, i think this is the best multiverse fanfic i've read so far. [5.0] ===== Character design: the mc is cool and fun. maybe not the most unique guy ever, but he’s really well-written—and that’s enough to cancel out any potential issues (not that I’ve had any yet). the rest of the cast is just as solid. the author doesn’t downplay or overhype the og protagonists—he actually makes them feel like real people. same goes for the side characters and the heroines. like i said earlier, the writing’s just damn good. [5.0] ===== World background: it’s a multiverse fic, sure, but the worldbuilding here is still better than a lot of fics that only stick to one setting. the important stuff gets explained, no pointless filler gets dragged out, and the pacing of each world’s development is on point—it wraps up when that satisfaction peak is hit. zero complaints so far. [5.0] ===== Final score: 5/5. maybe it’s not the most flawless or unique story ever to some people, but i honestly think it’s one of the best multiverse fanfics out there. it doesn’t feel like “suddenly too OP,” or “too weak for too long,” or “bad MC,” or “perfect MC.” it’s got its own vibe, and even if it’s not god-tier, that vibe is excellent. I seriously recommend reading at least up to chapter 32, where the 'the asterisk war' arc ends, and judging for yourself. but overall: highly recommend. :>
Well it is one of the best novel in this web novel It has good character development, world building and a really nice story so yeah it's op A solid 5 ⭐and please support this don't want this to droped
