[Western Crossover] Can You Keep Your Sister in Line?

Albedo, the Chalk Prince, an artificial human created by "Gold" Rhinedottir and her direct disciple, is now the Knights of Favonius' Chief Alchemist.

Before Albedo, countless failed creations were born from "Gold's" hands. Their creator placed them in a secret realm beyond the world.

One day, the secret realm was lost, and those creations ended up in another world.

Cleaning up one's master's mess is only natural for a disciple.

Albedo crossed worlds to deal with these lost creations.

After a series of twists and turns, he partnered with the Justice League to capture them.

But Klee, the little sister he had always looked after, secretly followed him when no one was watching.

And then, in the blink of an eye, she was missing again.

In Gotham, Tim had just located a human trafficking ring's hideout and was preparing to infiltrate it.

An explosion suddenly went off. Tim did everything he could to dodge it, but was still thoroughly buried under the rubble.

Tim: "..."

He was Timothy, handsome, refined, and well-presented. Even when supervillains knocked him down and left him sprawled on the ground, he had never been quite so disheveled.

"I'm sorry. My little sister has caused you trouble," said the man who dug him out of the rubble.

Backlit, the man appeared to have beautiful light golden hair and the gentle, refined air of a scholar.

He was sincere in his apology and compensation for failing to stop his sister from throwing bombs around.

He seemed like a reliable person. Tim relaxed and didn't take it too much to heart.

But after that, he kept running into the adorable-looking little girl, who was inexplicably obsessed with the "art of explosions."

Whenever the girl cheerfully shouted, "Jumpy Dumpty!" Tim had already started looking for cover on reflex.

The scholarly-looking man would show up every time afterward to apologize and pay compensation.

As ever, he was unfailingly courteous, with an impeccable attitude. He was also thorough in comforting and compensating the innocent bystanders.

Tim put up with it once.

Tim put up with it twice.

After the umpteenth time, Tim could take no more. He grabbed the man by the collar. "Mr. Albedo, are you ever going to get your sister under control?"
