I'm giving out a challenge for this community.

Plot: Kuroko Smith is the younger sister of The Great Explorer Smith. The Great Explorer Smith had gone missing for past two years. His last communication with the world was a phone call on his sister's told, "Monmusu's have risen."

Now Kuroko, being a highscholl girl doesn't have much of the prowess or resources at her disposal to figure out this mystery. One day in school Kuroko gets tackled by a girl with dog-ears. She says "I know about your brother, but we have to embark a long journey to find him."

This was the begining of the incident which brought about the Exchange and peaceful co-habitation laws, an adventure to find a lost brother, by none other than Ms. Smith.
