The clip comes from the first season of Re:Zero, the anime adaptation of Tappei Nagatsuki's light novel series, which first aired in Japan in 2016. Its first ending theme plays over the closing credits and became closely associated with the show's darker turning points and its return-by-death storyline. Short cuts like this one later circulated among anime fans for edits and tribute videos, because a few seconds are enough to signal the series to other viewers. It remains in use as a compact emotional shorthand for the show.
