Date a Live V

 Shido and his harem of mighty spirits are back in the fifth season of Date A Live!

And he still has to try and steal that kiss from Kurumi!

The story picks up immediatly after the previous season, with Shido confiding with the girls that he has died 204 times before, and Kurumi all the time rewinded events to save him.  As the DEM is still out to kill him though, he must start taking preparations to stop them.

The DEM fleet appears at their vessel, and battle commences.  They have managed to gain the support of Mana and Origami's old forces, but are still heavily outnumbered.  But as battle commences, Kurumi takes out a part of the enemy fleet, claiming she is coming to the DEM's leadership head as the city itself changes into a cannon heavy defensive line.

Together with Kurumi, Shido and the spirits start to overcome the enemy.  As they discuss the path to take, Kurumi offers her kiss to seal her should Shido defeat DEM, but then suddenly the Spirit of Origin brusts from Kurumi.  In a flashback, we learn Shido was originally called Shinji, who lived together with his sister Mana.  One day, a spirit is found in their home, and they call her Mio, Shinji taking her out on a date.  But she is hunted by Westcott and his men, and while they flee Shinji is mortally shot.  Mio absorbs him, in order to recreate him so they can be together again and swearing she will always be at his side.

Back to the present day, as a dead Kurumi tumbles to the floor, Mio manaifest herself.  Shido remembers what happened, but he doesn't approve her methods of sacrificing others for her goal, as Reine, who was a part of Mio's consciousness, merges back with Mio to complete herself again.  As the spirits are one by one defeated by Mio, Shido faces Isaac Westcott.  

Westcott tells him how he is actually one of the last remaining Magi, looking for vengeance against humanity for wiping out his people in the far past, and he created the Spirit of Origin.  Shido defeats him eventually, but Mio succeeds in absorbing the Seraphs of all the others, completing herself to reunite with Shido / Shinji.  But Tohka, being the only "pure" spirit apart from Mio, breaks free and engages her, even pushing her back before being erased by her angel.

A clone from Kurumi, send into the future intervenes and while defeated shows the way to Shido on how to defeat Mio.  By using Zaphkiel, he travels back to the past, asking Reine out on a date in an effort to seal Mio before she appears.  But the DEM and Westcott are also still in that moment in time, and having learned through Beelzebub they change their attack plan.

Shido fails to seal Mio, and as she manifests Kotori and Mana join him in facing off the forces of the DEM.  Kurumi assaults Westcott, taking and absorbing his seraphim, as Shido once again kisses Mio in an effort to stop her.  The result is that they end in an closed pocket dimension, where not only he and Mio are, but also Reine and Shinji as seperated entities.  

Shido confronts Mio with the truth about why he was created by her, as Westcott plays his last trump card: to become a Spirit of Origin himself.  Together with the other spirits they face him, but his powers go out of control.  This forces Mio to use her angel's cancelling powers on him, resulting in both being whisked out of existence, and her finally reuniting with Shinji in the afterlife.  

Awakening on the beach, Shido suddenly receives Reine's little teddybear, together with Mio's sepiraph crystal...

And so the fifth season (and the series?  I haven't read the light novels) comes to a close in which was a pretty intense adventure, definitly a highlight season in the franchise.
