Galdo's Sword 17
A cross-piece sword with a red gem on it's guard, white handle, and gold hilt.

The sword used to defeat Galdo Gasper in his gift game in Episode 3 - Sounds Like We're Doing All Sorts of Stuff in the Bath Together?. The gift game required a designated weapon to be used, namely, a specific sword found in Galdo's room.

The sword is used by Asuka Kudō to defeat Galdo, and is kept by her. Asuka's gift allows the sword's full power to be unleashed.
