This entry revisits Lord El-Melloi II, also known as Waver Velvet, who finds himself inexplicably regressed to his younger self as he prepares for a Clock Tower reunion.

Produced by TROYCA, the studio behind the original series, this special delves into mystery and urban fantasy as Waver investigates the cause of his sudden age regression. Fans of the original Lord El-Melloi II's Case Files: Rail Zeppelin Grace Note will recognize the blend of detective work and magical intrigue that characterized the main series, which itself is an expansion of the Fate universe.

While not a direct continuation, the special offers a self-contained narrative that explores Waver's past and personal anxieties. The 7.47 MAL score from over 16,000 voters indicates a solid reception for the franchise's focus on intellectual puzzles within a supernatural setting.
