Aldnoah Zero - ep21

Now as things are set for Inaho's rematch, things are much easier for him since this time he has the initiative. Although he didn't expect that lightning and invisibly would link up, it make things easier in some ways with reducing the frequency of the lightning attacks while reduces the mobility of the invisibility one. That through the use of his eye he is able to predict their behavior and in doing so he is able force them to split up by using Rayet as bait to draw the enemy into Yuki's line of fire. Now with the enemies divided Inaho is able to nul the electric attack by functioning as a lightning rod. Which allow him to take out the most troublesome one first. The second one is dealt with shortly after since it's general location was already known. The last one was the most bothersome since it could clone itself endlessly. Which means that only way it could be defeated is if they were all destroy at once, which puts a strain on Inaho from over using his eye. Now with this victory things are moving towards the final battle.

Then while all this was going Lemrina is confronting Slaine about his lie without reveling that she knows the truth. That with continuing his lie it leads to a face to face meeting of the sisters, where it appears that Lemrina is going to kill Asseylum so that she can permanently take her place. Although this doesn't happen instead they switch places by having Asseylum impersonating Lemrina to get answers from Slaine. However this get the answers she seeks it also results in Slaine placing them both under house arrest. Now with these event that it appears that Slaine is going die regardless of what he achieves either Inaho will kill him in battle or Asseylum with execute him when he returns her to power for going against her will and that day doesn't seem far off with Deucalion planned trip to the moon.
