Lost Memory

Lost Memory (ロストメモリー) is a Keyblade that can be wielded by Ventus in Kingdom Hearts Birth by Sleep.

Ventus obtains this Keyblade at Destiny Islands after he remembers his past as Master Xehanort's apprentice, and realizes Vanitas's origin.

Design
The Keyblade overall is an ivory color in varied shades, excluding only the small dash of deep red in the teeth and the Keychain, and the black in the handle and hilt. The shaft begins in two from a small heart shape on the end connecting to the handle, much like Oathkeeper, joining halfway down and ending in Ventus's repetitive fleur-de-lis, as also seen on his Station of Awakening. The handle bears the design on fully outstretched, upward-pointing angel wings. The Keychain repeats the design of the teeth, which consist of a crimson heart with a portion broken off, referring to Ventus's reawakening after the extraction of his darkness in the form of Vanitas. Around it stretches an angel wing on the right side, opposite the broken side of the heart, on which side is a slightly darker-colored flowing crest. The Keychain resembles the teeth as a winged heart.

The Lost Memory's name references Ventus's own lost memories of his past with Xehanort and Vanitas.
