With Class Cards In Another World

Roman Ofnir knows he teases a lot, but it doesn't mean he should be sent to a World War with Magic and Swords!

Fortunately, he was given a 'cheat'.

Class Cards.

Armed with the another world's best Heroes, Killers, and Villains, he will survive in this wartorn World if it's the last thing he does!
