As Yuma and co head towards the location of the second sealed Number, Vector goes to see Number 96, who has been possessing a corrupt official, and convince him to join up with him in his search for the Numbers. Arriving at an abandoned castle, Vector feels an odd connection to the place, like he had been there before. As Yuma's group arrives, Rio feels a similar sensation, speaking of a legend behind the castle. Vector and Number 96 reach the central colosseum, where Number 96 comes face to face with the Number's guardian. After accidentally triggering some traps, Yuma's group also wind up in the colosseum, where Vector arranges for a duel between Astral and Number 96, who had obtained the sealed Number. Number 96 instantly summons out Dark Mist whilst Astral summons Utopia, managing to use Dark Mist's ability against him. However, Vector reveals that damaging Number 96 activates some of the colosseum's deadly traps, which are aimed right at Yuma. (thetvdb.com)
