(The outline has problems and needs a rewrite. I'll repost once it's fixed, TAT.)
Qingqiu is a top-ranked veteran at the Time and Space Transmigration Bureau, now retired.
In accordance with his retirement wishes, the Bureau's headquarters specially arranged a new world where he could enjoy his retirement. They also packaged up a supernatural ability and a cursed technique suited to the new world as his retirement gift.
[Supernatural Ability: Their Blessing
Effect: The user is completely immune to supernatural ability attacks and gains an absolute luck buff. This is not a passive skill; the user can choose when to use it.]
[Cursed Technique: Their Blessing
Effect: The user is completely immune to cursed technique attacks and gains an absolute luck buff. This is not a passive skill; the user can choose when to use it.]
[This is a hundred-percent blessing from the gods for you. Their blessing surpasses every curse in the world.]
With a new identity unlocked and a new life to enjoy, Shigure Qingqiu's retirement in a new world officially begins!
But does this new world really make it that easy to pick up little brothers?
They're anywhere from six to sixteen, and they all have either supernatural abilities or cursed techniques?
Fortunately, these little brothers are all adorable. They're just a bit too clingy with him as their big brother...
(The entire novel is free.) (About three to five updates a week.)
(A crossover with Bungo Stray Dogs and Jujutsu Kaisen, perhaps with a few other series. No pairings in the main story; extras undecided. Apologies for the original settings and any out-of-character portrayals!)
(I watched these series a long time ago, so some details may be off! The timeline also has original elements. The author just wants to see brothers being affectionate with each other~)
Theme: Love is the true blessing given to you
