Shangri-La Frontier 5 (manga)

Having survived a fierce attack by one of the Shangri-La Frontier PK clans, Sunraku goes into the fighting ring against ten powerful monsters as part of a unique scenario. He barely escapes with his life, only to then receive an invitation from his gamer friend Pencilgon to help her take down a unique monster known as Wethermon the Tombguard. With Wethermon still undefeated by any of the game's 30 million players, Sunraku may have bitten off more than he can chew!
