P.S. This role is for both actors and actresses.

In the first part of Alicization arc, Kirito enters the Underworld and relives a new childhood along with two other kids he meets named Eugeo and Alice Zuberg. During this time, he and Eugeo mostly swing an axe on a Gigas Ceder and have picnics with Alice from her own cooking/baking. Although it is Kirito, he's a kid showing that innocent youth and doesn't have any memory of his past life in the real world or any trauma. He tends to be lazy, tease a lot, complain and is a huge glutton.
