Yuuta

Yuuta is the Z-Loan office assistant, who has the unique ability to heal. His job mostly consists of data-gathering, medical treatments, answering phones, and making tea. He likes to joke around and often pretends that his hands, which he named Ken Ken and Kon Kon, can talk. He is a zombie-loaner as well.
