Fan:Crest of Harmony

The Crest of Harmony (優しさの紋章 Yasashisa no Monshou?) is embodied by Kiyo Asukima. Its emblem is a stylized rose bud.

It is the Tenth Crest found, initially corrupted into being the energy source for the Digimon Emperor's base. The Harmonious Ones use it as the base of the Digi-Egg of Harmony, and it is found in its true form after the battle with Frigimon. Though it is never used to Digivolve Alchomon and its Tag is never found, it is used by Ken in an attempt to shut down the Digimon Emperor's base.

Strangely, this Crest (in both the English and Japanese versions) shows a form of sapience. In two episodes, The Darkness Before Dawn and The Crest of Kindness, the Crest speaks to Davis Motomiya, telling him that it believes in Ken and wants Davis to believe in him too, according to what Davis reveals to the others later. Davis even surmised by that point the crest was a manifestation of the goodness that was trapped in Ken, and as a result trusted it and Ken. In the Japanese version of The Crest of Kindness, the Crest speaks again after the defeat of the Emperor and only Davis can hear its voice, and he says that he heard a voice saying that it wished to return to where it truly belonged. The Crest then flies over to Ken, who is now free from the evil of the Emperor.

An amnesiac Ken takes the crest with him into the Digital World when he goes looking for Wormmon and his heart. Arriving in Primary Village, a Poyomon explains to him that this is the place where all Digimon are reborn and Wormmon would be there. Initially excited, Ken is unable to find Wormmon as he can not remember what his partner's Digi-Egg looks like and then is verbally hurt by the words of the baby forms of his former victims who are upset at him since he was the Digimon Emperor.

Realizing the cruelty he caused and the fact he can not remember any good memories, he forces himself to remember the first time he came to the Digital World and met Wormmon. Pushing past the residual influence of the Dark Spore, he is able to remember the person he used to be and the promise he made to Wormmon to always be that person. Sad that he broke the promise, he vows to himself that he will try to be the kind and gentle person that Wormmon and his brother wanted him to be. This sparks a reaction from the crest, which glows and causes a nearby Digi-Egg to glow—the Digi-Egg containing his partner, reuniting the pair.

Its image is emblazoned on the Digi-Egg of Harmony, whose digivolutions may have the Crest somewhere on its body.
