Andrew Gilbert Mills

Andrew Gilbert Mills, known in Sword Art Online as Agil, is a veteran axe-wielder and merchant who runs a shop in the city of Algade on Aincrad's 50th Floor. Outside the game, he owns a coffee shop in Okachimachi, which his then-girlfriend Trish kept running throughout the two years he was trapped, a fact that surprises him once he finally logs out.

Reliable and even-tempered, Agil looks out for the wider community of players rather than only his own guild, publicly defending former beta testers against Kibaou's accusations early on and quietly using his profits to help lower-level players gear up. Kirito considers him one of the more trustworthy people in Aincrad, someone who acts like a hard-nosed businessman while actually giving most of it away.

After the game is cleared, Agil continues playing ALfheim Online as a Gnome and remains part of Kirito and Asuna's close circle of friends, often serving as the group's calm, grounded voice of reason.
