This skin is unique because it includes Tsuna Sawada in his base form, with his Vongola Mittens. They are removable and this skin looks much better in 3D.
You can find him in his Hyper Dying Will State here.

Tsunayoshi "Tsuna" Sawada (沢田 綱吉, Sawada Tsunayoshi) is the main protagonist of Katekyō Hitman Reborn! Although at first a cowardly and useless junior high student, Tsuna is suddenly thrown into fulfilling the role as the tenth generation Boss of the Vongola Famiglia, the most prominent Mafia Famiglia in the world, forcing him to gather his own Guardians to eventually battle for the survival of the world. His character development from a weak individual who easily gives up to a leader dedicated and willing to fight for the protection of his friends, family, and Famiglia is a critical element of the series.
