REBORN! Future Final Battle Arc episode 196 (2010)

About

The explosion resulting from their last attack gives Gokudera the advantage. An attack from Bluebell injures Gokudera and she releases her carnage box intent on killing him. The Varia arrives in time and intercepts the attack. Meanwhile, Ryohei engages Kikyo in battle and is overwhelmed by Kikyo's box weapons, the Cloud Velociraptor. Ryohei asks Lambo if he wants to see Tsuna's mother, reminding Lambo they need to win the battle in order to return home. Lambo releases his Vongola Box in a rage and transforms it into its cambio form, Lampo's Shield. Using the shield, Lambo sends out a surge of electricity defeating the velociraptors.
