Fairy Tail Omnibus 2 (Vol. 4-6)

"S" is for screw-up. S-Class quests are so dangerous that one false move means certain death! Now Fairy Tail's loose cannon Natsu, rookie Lucy, and nearly powerless Happy have embarked on a stolen S-Class quest, setting out for the Demon Island, where a tale of tragedy threatens to repeat itself, and a strange new wizard keeps threatening to wander around in the nude. Can anyone stop them before the sacrifice of a great wizard gets negated entirely--and they get themselves killed in the process? Rejoin the guild, just in time for the return of the classic anime!
