Ryuuzaki, Kenichirou

Kencho was a Real Estate Agent and is Akira's best friend from the rugby club during their college/university days before the zombie pandemic. Their friendship drifted apart due to Akira's jealousy of his apparent success; unbeknownst to Akira, he constantly had to mask his dissatisfaction of his job and hated himself for becoming someone unethical due to the nature of his work.

He reunites with Akira after communication lines have been restored and was able to be rescued by him at a love hotel in Shinjuku where he was trapped in for 3 days. They mend their friendship and Kencho joins him in his journey across Japan to fulfill their bucket-list.

Kencho is quite the womanizer. His true aspirations is to become a stand-up comedian. His brand of comedy usually involve naked jokes.
