Shangri-La Frontier 2 by Ryosuke Fuji

A fast-paced, irreverent adventure for fans of isekai and RPGs! High schooler Rakuro loves hunting down "trash games," but one day he decides to play a AAA VR game called Shangri-La Frontier instead. He creates a character with a bird head, skips the cutscenes and jumps right in--but what awaits him in this game is different from anything he's ever faced...

NEW ENEMIES, OLD FRIENDS

After diving into the god-tier VR game Shangri-La Frontier, Sunraku (a.k.a. Rakuro Hizutome) suffers a crushing defeat by the unique monster Lycagon the Nightslayer. Sunraku comes away from the encounter with a mark that prevents him from equipping anything on his legs or torso. But don't count him out yet! Joined by Emul, the gregarious vorpal bunny, he presses on along a path that will bring him face to face with terrifying new foes, and even some familiar names from the gaming world.
