Hibari: A soft, adorable carnivore.

Ichigo: She's my little sister, the only girl in the Kurita family. (And probably the only girl who's a sword freak, too!) So cute.

Tamamo-no-Mae: My pillow.

Gaara: With her around, I never have to worry about my dark circles again.

Isana Yashiro: Whoa! I don't remember who I am either!

Currently confirmed fandoms: Detective Conan, Katekyo Hitman Reborn!, sword freaks, Onmyoji, Naruto, K, and others.

The order is undecided.

[Original blurb]

After being forced to drink a drug by members of the Black Organization, she was in agony and thought she was about to die.

Then she transmigrated and was adopted by a man named Hibari Kyoya.

From then on, she had an incredibly, incredibly, incredibly overprotective big brother!

Every time there's a parent-teacher meeting:

Teachers & parents: I-Izumo, Hibari!

[W-were they suddenly caught in a gathering?! B-but this is just a perfectly normal activity! (About to lose it)] QAQ!!

**

1. The heroine transmigrates into Detective Conan first, and only later into Katekyo Hitman Reborn!.

2. The heroine is a sweet, naive girl with maxed-out combat ability.

3. The heroine should have a [passive brother-finding] setting.

4. The heroine comes with a childlike aura that makes every childish thing seem reasonable [everything she does fits her age] and so on...

5. This is a story born from a wild imagination. If the protagonist seems really stupid... it's all my fault... Yes!

6. This is a wish-fulfillment story.

7. The author got carried away with the ideas and decided to write a crossover.
