Pastor of Tomorrow's Ark

"Medical operator! I need treatment!"
"How is Gavill?"
"I don't want to be 'peaceful'!"
"How is Fafa Lin?"
"I don't want to be bled!"
"Then... how about Bai Ye? He must be able to!"
"Bai Ye... He followed Huang with his sword and rushed out!"
This is the story of a sickly (not) boy who travels to the world of Terra to become a furious tutor.
