Arknights: Soul Knight

Four college students playing Soul Knight find themselves transported to Terra due to their roommate's vow to draw cards. Their unusual appearances lead them to be mistaken for Sarkaz upon landing.

They are respectively

The Paladin Elder Brother of Rhine Lab (Skin: Hellsword. Greg)

"Is this the power of the Balrog!?"

"Flame Demon? Who?"

The second Necromancer boss to land in Kazdel (Skin: Orange Flame Demon Eye. Vera)

"The corpse has stood up! Is this a Word of Power? She's a banshee!"

"[Chinese profanity!] Where's my brother?!"

The third Druid who landed in the Ursus snowfield (Skin: Forest Envoy.Gus)

"Hiss... Wendigo?"

"Don't come any closer!!!"

The fourth vampire to land on the Iberian coast (Skin: Red Shadow Judgment. Vayne)

"Brothers, it seems like we've traveled through time."

"You don't need to say that!!!" x3
