Caeli Vas Deo/Relationships

Caeli has developed many relationships over the course of his journey within his own cells, the Occult Research Club, the Student Council, and the Three Factions . He's also attracted the attention of many female characters, much to his personal chagrin.

Lucina Faustus
Lucina is Caeli's familiar and one of his closest companions. While Caeli was initially averse to Lucina staying by his side due to his own personal reasons and wished for her to stay away from him, though Lucina herself very much objected to that notion.

Lucina tends to be Caeli's voice of reason when some of his other tendencies come up and he needs someone to straighten him out and get him in line, and he really does appreciate her support. Caeli is also very well aware of Lucina's feelings for him and how he is her central emotional pillar, no thanks to how many times the girl has stated he's the only reason she has to exist, which initially triggered his heroic side to the point he injured himself to suppress it.

Caeli starts to become very protective of Lucina as his bond with her grows closer and closer, and will outright snap at any insult directed towards her or if she is ever injured, as shown when Rasier Phenex insulted Lucina in front of others, which resulted in Caeli angrily snapping at Raiser both verbally and physically.

Caeli feels himself started to develop feelings towards Lucina (as well as the rest of the girls in his group) after being pulled away from her due to the loss in the Rating Game, realizing that he relied on her much more than he thought.

Kuroka
Caeli took Kuroka in while she was in her guise of a black cat he named Noir. Caeli was initially rather suspicous due to Kuroka beng an SS-Class Stray Devil, though he was willing to allow her to remain at his home since he had taken her in, and as such, he saw it as his responsibility.

Caeli tends to get easily embarrased around Kuroka due to her flirty nature and tendency to invade his personal space, but also relies on her as much as he does Lucina, and he does genuinly care about her a great deal, willingly going along with some of her more tame desires (mainly simply petting).

While Caeli doesn't exactly acknowledge Kuroka's claims of her being his mate/bride, he does recognize her feelings for him, and even returns them to a degree.

Astra Ruby
Caeli initially thought of Astra as little more than an annoying brat who did nothing more than follow him around looking for a fight. Caeli enjoys teasing Astra to some degree since she doesn't understand her feelings towards him and likes to make jokes about it due to her dense nature.

Though, like with Lucina and Kuroka, Caeli found himself growing fond of the hot headed Fallen Angel after some time, and he eventually starts treating her as something like a little sister due to her younger age, and Astra herself sees him as an older brother figure at times.

Out of most of the girls Caeli has to deal with, he has the hardest time with Astra due to the fact he simply sees her as a younger sister more often than not, but he is willing to recongize that she is indeed a young woman.

Issei Hyodou
Caeli and Issei have a relationship that can be described as "not-quite-friends-but-more-then-rivals".

The two have a mutual respect for one another, though Caeli does get a bit of a kick out of reminding Issei which of the two of them is the stronger fighter. Caeli is greatly annoyed by Issei's perverted antics and personality, who in turn has problems with how Caeli's borderline asexual nature makes him bar none the least perverted person Issei has met.

But, Caeli does acknowledge the power Issei has and the two of them begin to develop a more "teacher and student" friendship after Caeli returns from the Underworld, Caeli teaching Issei more about his powers and helping him get stronger as a result.
