Seraph of the End: Guren Ichinose: Catastrophe at Sixteen (Manga) 5 (manga)

With less than two days left before his father’s execution, Guren finally opens up to his friends and asks for their aid after watching Mahiru get whisked away by vampires. Together they set off for Kyoto to try to bring Guren’s crazed childhood love into custody, and on the way manage to capture a live vampire and a mysterious piece of cursed gear that Mahiru herself had been wielding. But will this major harvest be enough to spare Guren’s family and followers from the guillotine hanging over their heads?

Meanwhile, time is quickly running out before the foretold catastrophe on Christmas. Guren helps the Hiragis launch a full-scale war to wipe out the Brotherhood of a Thousand Nights and put a stop to their Seraph of the End project, but all is not what it seems...
