Juuou Mujin no Fafnir - ep10

Now it seem like they are just trying to draw thing out as long as possible since they do not attack Basilisk after the military fails. They instead create another plan to trap it by using Tear to draw it in and then have Tear leave the island to draw it's attention away from what they will be doing. That with it's attention diverted they intended to shoot it through the mountain. The rest of the episode focus's on the final preparations being made. Although you also have the fact that Honoka is acting suspicious in her actions towards Tear so it is possible that she is Kiri.

That there are further hints at this fact being that Fyril noticing the amount of Dark Matter that Honoka was feeding her during the operation. There is also the issue on how the Basilisk knew that they were going to shoot it through the mountain and why it was already prepared to counter them. Another interesting point is that each time it fires it's beam Tear condition seems to get worse so in the end even if they do defeat the Basilisk, they still might not be able to save Tear. The major question for next time is how are they going to delay thing for another episode or will they finally end the fight with the basilisk and if they do what will they use the few remaining episodes for.
