Light of Hope

The Light of Hope in the anime

The Light of Hope (希望の光) was, according to the Sailor Starlights, the only way to defeat Sailor Galaxia in the final season of the anime and some of the musicals.

When Sailor Galaxia sealed Chaos within herself, she feared that it would someday overtake her. She removed her Star Seed and sent it off to the far reaches of the universe, hoping that someone would receive it freely. When it came to Earth, her Star Seed found Usagi Tsukino and took the form of Chibi Chibi in order to be near her.

In the final episode, the Light of Hope took a form that appeared very similar to that of Sailor Cosmos in the manga. She offered her aid to Sailor Moon in the battle against the Chaos-possessed Galaxia, taking the form of the Fuuin no Ken as a means to defeat the powerful Senshi. Sailor Moon, however, refused to fight, and the sword was shattered; it resumed the form of Sailor Chibi Chibi Moon before disappearing.

After Sailor Moon finally triumphed through the power of her own love and the Star Seeds were freed, Chibi Chibi reappeared and departed for places unknown, presumably to rejoin her former host.
