Lagrange: The Flower of Rin-ne

As the darkness continues to spread across the earth, Madoka, Lan and Muginami wake up seperated in a strange place similar to where she first met Yurikano. They each come up against a vision of Dizelmine's Vox and fight angrily against it. Meanwhile, Asteria confronts Moid, who reveals he manipulated Dizelmine into opening the Rinne, revealing his motives before receiving a prompt punishment from Yoko. As Madoka sinks into despair over being unable to defeat Dizelmine, she gains encouragement from Midori and is shown a vision of Dizelmine and Villagiulo's past, before managing to find Lan and Muginami. After regaining their resolve, the three resume their battle against Dizelmine, aiming to make him remember the goals he shared with Villagiulo.

Madoka has her hands full as, on top of her usual Jersey Club requests, she has to sort out her post-graduation plans and organise a party for Kirius and Array, who are to leave for their home planet. Meanwhile as Nomundus investigate the whereabouts of Moid, Asteria tells everyone about her involvement in the 20,000 year old tragedy, revealing her real name to be Maycun, a former queen of Le Garite. After a full day of fulfilling requests, Madoka comes down with a fever. As Lan and Muginami look after her, they worry about how to tell her that they intend to return to their home planets once they graduate. As Madoka recovers and joins in the farewell party, Asteria contacts Villagiulo for information on Moid and comes to realise something about him whilst Dizelmine undergoes a Vox Control Particle Experiment under Moid's suggestion. After Kirius and Array take their leave, the Le Garite fleet suddenly appears above Earth and fallen De Metrio ships land upon Kamogawa.

After Madoka knocks some sense into both of them, Dizelmine and Villagiulo agree to work together to resolve the threat to their planets, announcing their unionship at the Intergalactic Conference. The next day, Dizelmine and Villagiulo settle things with Lan and Muginami before setting off. As the Novumundus crew discuss what caused the Voxes to act on their own, Madoka, Lan and Muginami return to the place where Madoka and Lan made their vow to meet again, this time to make a vow not to use their Voxes as weapons ever again. As Yoko demonstrates a new section of the tablet her team are deciphering, Asteria sees a disturbing vision, revealing to Yoko that she herself was responsible for the tragedy that befell Earth 20,000 years ago. .

As the girls arrive on Le Gartie's ship, Dizelmine explains why he kept Yurikano's presence on the ship a secret from Lan. Later, Dizelmine brings Madoka to where Yurikano is, putting her in an experiment to implant her mind into Yurikano's body. Realising what Dizelmine intends to do, Lan divises a plan to distract the Le Garite troops whilst Muginami goes to rescue Madoka. As Madoka and Yurikano's consciousses meet again, Madoka feels Yurikano shouldn't need to sacrifice herself for other people and decides to fight her to get her to tell Dizelmine and Villagiulo how she truly feels. As the Le Garite ship starts to become covered in a strange red substance, the Vox units launch whilst Yurikano wakes up in Madoka's body.

As Kamogawa prepares for an intergalactic conference, Asteria calls Madoka, Lan and Muginami about a Vox Particle Control Experiment, the same that Dizelmine attempted on Lan. She explains about how she wants to try to use the power of the Voxes in a peaceful way to put Villagiulo and Dizelmine off their plans. Madoka agrees to undergo the experiment, and although the initial attempts show no reaction from her, Asteria manages to prompt a reaction from Madoka by embarrassing her. However, as they attempt to stop the experiment when Dizelmine and Villagiulo attempt to contact them, Madoka's levels continue to rise, causing a strange red phenomenom to appear in the sky, which starts forming strange creatures. Meanwhile, Madoka is haunted by visions of what appears to be Yurikano, warning her not to open the Rin-ne flower. When Madoka regains her sense, she finds all the creatures had been destroyed and more Rinne flowers have appeared.

As Madoka contemplates her career options, Lan is on a space station being experimented on by her brother, Dizelmine. Just then, the station is attacked by the De Metrio army, led by Muginami, forcing Lan and the Le Garite army to retreat. The next day, as Pharos appears in Kamogawa again for an intergalactic conference, Madoka finally reunites with Lan, who takes her to Pharos asking her to pilot Midori again. As Muginami is seen approaching Pharos, intending to stop Madoka from piloting Midori, Lan engages her in battle, believing she intends to kill Madoka. As Madoka objects to the fighting, she manages to get Midori working again and enters the fray.
