Cúchulainn: You take no pains to hide your wonderment. How I shall delight to watch you die. Each excruciation ecstasy!

This is Cúchulainn the Impure, one of the twelve Lucavi demons. He resided in the Scorpio stone, the stone that Delacroix held when he first met the party.

Cúchulainn bore a rather similar design when he appeared in XII. In both appearances, he represents the element of poison. There’s a common belief that Scorpios have “poisonous” personalities, and many of the villains in Tactics do fall under the Scorpio zodiac sign.

Cúchulainn is the only Lucavi without any sort of Biblical or religious roots. While most of the other Lucavi mentioned in Tactics are variations of Jewish or Christian demons, Cú Chulainn is a figure in Celtic folklore. One can suspect that when Christianity was introduced to Ireland, the old pagan myths were often cast aside as being “evil.” That may have been where Cú Chulainn came to be seen as more of a wicked being, rather than a mythical hero. The following text was sent to my friend glabados in an ask:

Re: your write up of the religion of Glabados: Cuchulainn may have later been seen as a demon by the Catholic Church (though it’s really not anywhere in the Bible) as originally he was a mythical figure in Celtic/Gaelic mythology. Cuchulainn was a demigod, the son of the sun god, Lugh of the Long Hand. I would suggest looking into this a bit, just for interest’s sake; I, personally, find Celtic/Gaelic mythology absolutely fascinating. Dunno why he would be inspiration for a Lucavi, though.

While he’s not my favorite Lucavi/Esper, the design for Cúchulainn is absolutely fantastic. His “impurity” makes him a good fit for Cardinal Alphonse Delacroix, especially since a holy man is supposed to keep himself free of corruption. The evident sins that Delacroix has committed are especially prominent, considering his station. His own impurity is obvious, very much like Cúchulainn.
