This is a TVRip made over a decade ago that I found being mislabeled as “Episódio 770 - Simulacro de Despedida [Animexpt]” on old storage.
This is Episode 1772, which is a 23 minute long Special episode. The Japanese title is "ためしにさようなら " (Tameshi ni Sayonara).

It is ripped from Canal Panda, having a Spanish (Castilian) audio track and Portuguese (Portugal) Hardsubs. The name of the ripper/encoder is unknown.
