[Western Crossover] The Wayne Family’s Guardian Spirit

Third-version blurb [Moonlit Masterpiece ver.]

“, Tell me, are you my Master?”

Moonlight fell quietly on the mother holding her son close and the silver-haired fairy, just like the miraculous moment on a winter night in another world when a certain girl met a certain boy.

“Servant, Caster, answering your summons. From this day forth, my sword is yours, and your fate is bound to mine.”

“Thus, our contract is complete.”

“Master, please give your orders.”

Second-version blurb

Red Robin: Before you stands B’s first partner on night patrol, Gotham City’s uncrowned king, the only purely magical being among Gotham’s vigilantes, and the second most important lady of this household.

The youngest Robin: There isn’t room for this many people in the Batcave.

The Black Bat: When did they find out?

Fairy Knight: We never tried to hide it from them, did we?

Red Robin: I never realized that the three years I spent living in this house were the most eventful of my life

Nightwing: ...So of course aliens need to be kept under control too. There are already three nonhumans in this household under B’s supervision. It’s completely understandable that B would prepare contingency plans A to Z for the Kryptonians.

The Butler: My dear young masters and misses, it’s dinnertime. Could we leave everything else until after the meal?

The whole family: Alfred!!!

The youngest Robin: Wait, shouldn’t you be the most important lady of the household?

Fairy Knight: The most important lady at Wayne Manor is, of course, Mama Martha.

Original blurb

After the gunshots rang out, a family of three entered Crime Alley. When they left, there was one more person with them.

P.S.

1. The worldbuilding is primarily based on Type-Moon [apart from the characters and place names, it contains no DC worldbuilding. It’s better to think of these characters as appearing in the Nasuverse, rather than imagining the Nasuverse and other works’ settings being combined];

2. The female lead has the innate yuri tendencies of Fairy Britain early on [there are no actual related events or romantic developments; this exists only as part of her characterization], and she’s a big fan of Morgan;

3. In this story, the dark and brooding father has both parents alive [I’ve taken plenty of liberties with the setting, so if you can’t get into it, you’ll probably be happier just dropping it];

4. Gotham City really is a peaceful and friendly place [by the ending, it should be completely transformed];

5. The two families’ parents will meet, with the Bat-family and the Avalon family sitting on opposite sides of the table for a meeting;

6. There will be a great many Moriartys in this story;

7. I can’t guarantee that readers unfamiliar with the works involved will understand all the related content [but I’ll do my best];

8. I’ll add more if anything else comes up. That’s all for now.

Theme: Building a civilized and friendly community
