Guess that anime

So this is game of where you explain an anime badly and the other's have to guess it

So ex:
A 13-year-old boy loves his demon butler
Another person will guess the anime
Black Butler
If they get it right they say an anime and so on and so on.

A kid runs around with a corgi and multiple adults.

Cowboy Bebop

Aye!

Two kids abandoned at a church, but only one is the only powerless one in the world with an anti-magic sword.
