[JoJo's Bizarre Adventure] Can Familiars Slay Demons in the Taisho Era?

Synopsis:

Because of a botched spell cast by a Void Mage, an ordinary girl is unwillingly summoned to another world.

Knowing nothing about where she is or how to get back, she gradually begins learning the language, housework, swordsmanship, and all kinds of strange knowledge.

But just as her survival becomes uncertain, she discovers that, perhaps because of a residual spell from the summoning, she can use all sorts of strange, lethal weapons and travel through time and space by kissing someone, as if sealing a contract.

To uncover the truth, she slowly turns to look at her friends in silence.

Everyone can't help covering their mouths.

3. Major changes to the source material and lots of out-of-character behavior.

4. A growing protagonist, accompanied by all kinds of tangled emotional relationships.

5. Multiple worlds merge.

Theme: A girl and her growth
