Lumineuse

 Lumineuse (リュミヌーズ) is one of Larxene's weapons in Kingdom Hearts 358/2 Days. It can be upgraded to Lumineuse+.

Design
An Eruption knife's blade is two-pronged and fans outward slightly. The blade is yellow at the tips and blue at the base, and the two colors blend together. The outer edges of the prongs are black. The handle is shaped like one of the spikes on the Nobody logo and is navy blue. Except for the differing color scheme, the Lumineuse knives are identical to the Eruption knives.
