This is the stretch where the anime finally stops apologizing for itself. The first twelve episodes threw you into Suwahara City with Ren Fujii in a hospital bed, guillotine dreams, black-clad knights, and Shirou's line about everyone here losing their minds, and then mostly refused to explain any of it. These six web-only episodes are where the LDO ritual out of burning 1945 Berlin actually starts paying off, and the fights get the animation and the BGM they were always writing checks for. Yes, the artstyle still looks like it wandered out of an older decade, and yes, half the cast reads like Fate archetypes wearing new coats, Gate of Babylon energy included. If you read the visual novel, you already knew the payoff was worth waiting through the confusion. If you dropped it at episode 6, this is the part your friend kept telling you about.

These six web episodes continue Dies irae, covering episodes 12 through 17 of the story, which were streamed online rather than aired on television. The setup comes from the earlier entry: in Berlin in 1945, Nazi officers stage a ritual meant to call forth the LDO, destructive supermen, and whether it worked is left unknown. In present day Suwahara City, student Ren Fujii has spent time in the hospital after a violent fight with his former best friend Shirou. A string of beheading murders grips the city while Ren is plagued by nightmares of dying under a guillotine, and harsh battles lie ahead in this action series.
