On the day before the school festival, Hagino returns to the dorm. Everything is finally coming together for their performance, including the costumes for all the characters, and Yuuko is so moved by all of this that she almost cries. They need more time though, so Yuuko gets them permission to use the auditorium through the night. Meanwhile, on the Novaal, Shivariel calls together a meeting with the other captains to go over how the main invasion fleet is setting out soon. The more pressing matter for her though is the Blue and its commander, as Azanael points out as she interrupts. Azanael has figured out that Shivariel had planned the accident on the Blue in order to study the effect of the Emil Force Drive and the telepathic waves. She accuses Shivariel of trying to destroy the evidence by destroying the Blue, and when Shivariel doesn’t deny it, Azanael rushes to her side and pulls out a gun. To avenge Onomil, she proceeds to blow a hole in Shivariel’s head. To everyone’s surprise however, Shivariel dissolves, but she just as quickly reforms and reveals that the true objective was to verify the substance produced by the critical reaction, the thought condensing weapon. With everyone in the room now after her, Azanael throws a grenade and makes her escape.
Back at the school, Yuuko privately meets with Hagino and pulls a gun on her. Having seen Hagino talking with Mari by the pool earlier, Yuuko now confronts her about being an alien. She’s quickly reduced to a state of disbelief after Hagino reveals that a large-scale fleet will invade in a few days. Hagino, however, claims that she personally wants to protect this planet. Unbeknownst to both of them, Michiko had accidentally overheard their conversation and runs away in shock. Meanwhile, on the Novaal, Azanael is caught in a firefight with a bunch of the guards when she suddenly hears Onomil call out to her. She drops her guard long enough for Onomil to hug her, but Onomil then reveals that she’s created by Azanael’s mind – an embodiment of her desires and fears. More Onomils appear, combining into one big lump, and Shivariel then reveals that this is the thought condensing weapon. With it, Shivariel thinks that they’ll be able to control the humans through their inherent fears. Azanael tries to run away, but she gets shot by the guards and falls. Though unconscious, Azanael remembers getting a pendant from Onomil back when they were together. As her blood now flows onto the pendant, it activates and signals her personal fighter aircraft to open fire in the hanger.
As for the festival, it starts without a hitch, and everyone’s relatives come, including Mari’s grandmother. Watching over the festivities, Tsubael comments to Hagino on how the humans have a strange existence. They’re so tiny and weak, yet they completely changed Hagino, and Tsubael admits to being a little jealous of that. Hagino feels that she’s not the only one’s who’s changed and watches as Mari walks towards her. The two then go back to the pool area to finish their discussion, and Mari questions why Hagino didn’t tell her earlier. Hagino admits to being afraid because she let a lot of people die back then, and at a time when she wasn’t able to do anything, she met Mari. She had been surprised to find out that Mari survived, and it made her very happy. When Hagino reveals that didn’t tell Mari the truth because she was afraid, Mari responds by slapping her and then pushing her into the water. Mari claims the slap was for not telling her properly and the push was for worrying her up until now. However, she then jumps into the water with Hagino, and two kiss as they confess their love for each other. Watching from the stands, Tsubael notes that it’s better for Hagino to smile after all.
Out in the ocean, Azanael escapes via her own fighter aircraft, but Shivariel decides to ignore her so that the fleet can go after the Blue instead.
Okay, that was probably the most exciting Blue Drop episode to date. Never mind the fact that we have Hagino and Mari making up and getting together in a kiss scene that reminded me a lot of a similar scene from Strawberry Panic, the invasion and Shivariel’s plans have finally come to light. I was actually really surprised when they showed Shivariel getting shot in the head since that’s not the sort of thing you expect from that kind of scene (I had thought Azanael would get stopped by the guards or something). However, Shivariel fooled everyone (including probably most of us the audience) with her use of the thought condensing weapon, and the invasion is proceeding as planned. And that brings us to how they end this series. Assuming that the aliens do eventually win, I think Hagino will probably be able to stop Shivariel, but not the invasion itself. The preview makes it sound like she might die protecting Mari, so maybe we’re in store for a bittersweet ending.
