Katekyo Hitman Reborn!

On Tsuna's side of the world, he is curious to know who is the Guardian of the Mist only to faint at the sight of Chikusa and Ken. At the Vongola Compound in Italy, an attempted recon mission is enacted by Iemitsu to find out what happened to Vongola the 9th. When Tsuna regains consciousness, he and his 'family' find out who is really the Guardian of the Mist.
