The espada ropera was a sword developed in the mid-15th century in Spain. The name referred to swords worn by civilians, as opposed for those meant for battlefield use. Compared to earlier swords, the espada ropera was lighter, thinner, and more ornate. It was first mentioned in an inventory of Don Álvaro de Zúñiga in 1468.
The espada ropera (lit. "dress sword") was the forerunner of, and in Spain a contemporary of, the rapier. The French term espee rapiere is a derivative of espada ropera. The espada ropera distinguishes itself from the rapier in that its blade, though thin, could be used to make effective cuts. Modern tests have shown it capable of cutting cleanly through a pig. These swords were manufactured mainly in Toledo.
It is a sword that stands between a Baroque period rapier and a late medieval arming sword and it is also considered to be the starting point of the light-blade lineage. The espada ropera has a cross-guard and despite the fact that the sword is narrowed it maintains an effective cutting edge.
In the fictional Bleach manga/ anime universe, a hollow (虚(ホロウ horō) is a monstrous ghost that ought to be slain and purified or else it will feed on other souls. Many of the series' antagonists are hollows; also, the fictional universe also has hollows with Soul Reaper(a death-related entity)-like characteristics called arrancars (破面(アランカル) arankaru, Spanish for "to tear off," kanji translates as "broken mask"). One of the series' main storylines has Sōsuke Aizen (the primary antagonist for the majority of the series) and his arrancars (particularly the ten Espadas, the strongest ones) as the force opposing the protagonists.
The creator of the series, Tite Kubo, used many Spanish motifs for the series' hollow-related elements. The fictional creatures have been praised by reviewers for the early hollows' strong emotional ties to their victims and the "interesting" concept of the arrancar; the visual appearance of the characters have also been commented on.
