Both of the fighting women flee leaving Aya and Natsume confused about what they just saw.
During lunch Miko finds Aya and Natsume and explains the fight as the Martial Heart and that her only wish is to won so she may have her wish… to have friends. Aya and Natsume offer their friendship immediately so that Miko no longer has to fight, and tell her she will have both of them as friends forever.
As Aya strolls home she receives a text message saying that due to Miko dropping out of the Martial Hearts she will now be a fighting participant in the tournament. The Fight Attendant returns at night and gives Aya a bag full of money and explains that the money is hers for being in the tournament and that she will defeat her in Mortal Combat.
