When the Varia, Vongola Assassin squad claimed the right for their boss Xanxus to be the true Vongola heir, they started a competition with Sawada Tsunayoshi in order to decide. To defeat the Varia, Reborn recruited most of Tsuna’s schoolmates to become the Vongola guardians, including Hibari Kyoya, the deadly head prefect. They were later joined by Lambo and Chrome Dokuro, a girl who has a mental and physical link with the criminal, Rokudo Mokuro.
It’s pretty awesome to have cast mates when you cosplay at a huge convention like Japan’s Winter Comiket 2010. Thanks to Neil for sending this in!
