Rinne no Lagrange Season 2

Synopsis

Madoka is oblivious when she steals customers away the haunted house designed by Kirius, Izo and Array. Asteria has a meeting with Tadokoro and Watabe, concerning the Vox Particle Control Experiment, the one attempted on Lan at the space station. The news reports that an intergalactic conference will take place in Kamogawa in one week. Before the summit, Asteria summons Madoka, Lan and Muginami at Pharos to discuss the experiment. Once Asteria shows them a picture of the Rubin vase, she explains that she wants to figure out a way to use the power of the Vox Units in a peaceful way in order to put Dizelmine and Villagulio off their plans. Madoka agrees to undergo the experiment, and Asteria manages to prompt a reaction from Madoka by embarrassing her after initial attempts show no results. When Dizelmine and Villagulio simultaneously contact Pharos, the experiment is ordered to cease. However, Madoka's levels continue to rise, causing a mysterious red fog to appear in the atmosphere and forming strange creatures. Meanwhile, Madoka is haunted by visions of Yurikano, warning her not to open the Rin-ne. When Madoka regains her senses, she is surrounded by destroyed creatures and bloomed Lagrange flowers.
