He then meet a pointed ear girls that looks like elf. She say her body get mutated since birth and her ear got affected.

His training was kinda brain training, he works at front of the computer, playing some strategy games and information thing.

After that his collagues tell him to take rest because he works to hard, they told him to go to this place and have fun.

There, she meet the translator, a local girl who translate japan people word to the local military thing.

She then told him she also works as prostitute, translato was one of her job too. The guy then refused to have sex with her, and ask her to teach the local languange as her pay than selling her body to him.
