Kari

When I think of light and lighthouses the first thing I think of is Hikari Yagami from Digimon: Adventure 01. :) She is the child of Light and I love her very much, she's pretty much always been my favorite. Naming this Ampharos Hikari seemed a bit too on-the-nose though because it's basically just the Japanese word for light, so I just used her English name, Kari.
