Well, someone is certainly happy to see us! It's Soma Schicksal from the God Eater series! Soma stands at 9.1" tall, and he's wearing his outfit as seen in God Eater 2. He's looking quite dapper in a white jacket, grey button-down, and loose yellow necktie.
The first human to be injected with the Bias Factor, Soma-kun has gained lots of tough experiences. This explains the stern expression on his face. Being a God Eater is no easy task, which is why he's depicted here loosening up that uncomfortable tie!
