Kuon/Relationships

Excellion
They were Kuon's only parental figure, the one that guided and nurtured him into who he is, along with an impossible ideal to aim for and the reason he exists. Kuon professes outstanding admiration and loyalty to Excellion, and they are the only person Kuon will take orders from.

Kuon is fully aware of all the death his mother has spread and glorifies it. No matter how much death, hatred, sadness and failure, for Kuon, Excellion will always be deserving of the seat of God.

Lucisfear
It has been theorized that Kuon may be connected to him, and Tael has implicitly questioned the fact that their faces look nearly identical.

Ishtar
Kuon is interested in the girl's development as a person now that she's left her obsessions (at least mostly) behind. He is currently disappointed with the fact that she seems to have established some sort of pact in order to gain power. He does appreciate her at least having ambitions of her own, and he is quite fond of her from the time they spent together in Caelum.

He is also perfectly aware of the little crush she's developed on him, but he chooses not to address it.

Tael
Kuon does not have strong feelings for Tael, but he is interested on figuring out his intentions and wishes as a free man. He does, however, have certain respect for him due to their time as soldier and instructor for the team of glaives back in Eos.

Astora
Kuon has noticed something amiss with Astora's identity and an increase in her paranoia, however, he has been convinced to stay as an observer for now. He has no concrete intentions for her, and, regardless of any past romantic interests, he has decided to show his affection for her as protection and guidance at her request.

Ciel
Although their relationship had a rather rough start due to Ciel's killing intent upon meeting him, Kuon harbors absolutely no ill intent towards her. A teammate is a teammate. After Ciel's experience with the distortion, Kuon has noticed a decline in her usual distaste for her presence and he is willing to start from scratch and form a proper bond with her, with no debts involved this time.

He is also quite impressed by her swordsmanship expertise at such a young age (although technically, she's older than him), and he considers her particular style to be quite beautiful.

Tatl
Kuon personally and privately requested that she be put on a team that did not include Tael. He is slightly worried that she might still be living based on other's standards and setting her own based on their supposed desires, thus, he observes her development with great interest. From their conversation atop the Great Archives, it is inferred that Kuon is also willing to form a proper connection with her, as they did not get to interact much during the events in Eos and Caelum.
