Reborn! 8

Junior high student Tsuna is a failure at school, sports, and social life. He needs a Mafia hit man tutor like he needs a hole in the head...and he's about to get both!
Students at Tsuna's school are being attacked, and it's up to Tsuna and Reborn -- on orders from the ninth generation boss of the Vongola Family -- to figure out why and take the culprit down. Then it's time for a lunch break, featuring the ever-deadly cuisine of Bianchi, who has a lesson in love to teach. But the big surprise is Tsuna's discovery that a member of his "family" has become a turncoat!
