At the beginning of the story, Kamito is lost in the forest. He stumbles upon Claire taking a bath. In an attempt to smooth things over, he assures her that he has no interest in children. Claire reacts poorly.
After the above fiasco, Kamito is knocked unconscious and wakes up with a whip around his neck, Claire standing over him. Noticing her embarrassment, Kamito promptly decides to tease her. The conversation is something like this.
Kamito: So you like tying people up?
Claire: N-no, I was....
Kamito: Then you like being tied up?
Claire: ......*starts crying*
Fianna at one point says her cooking is so good any spirit who ate it always went back without complaints. After trying it, Kamito notes that they must have been knocked unconscious, then adds it shouldn't be possible to do that to a spirit.
When Ellis gets flustered or angry at Kamito, she'll swing her sword at him while telling him to "turn into X", with X being some exotic food dish. Kamito promptly asks to try whatever dish she's talking about.
Ellis, the super-serious knight, has an I'm Taking Her Home with Me! reaction to small animals. Including Scarlet, Claire's spirit. Scarlet is understandably terrified of her.
On the same note, Claire likes to use Fenrir as a pillow. Fenrir doesn't mind, but Rinslet does.
Est is the only one of the girls who never seems to verge into Clingy Jealous Girl territory. At least, not until Restia shows up....
This leads to the two of them arguing in his head while they're in sword form.

Rinslets cooking. She's so good, she summons an Elemental Lord with pancakes. Even Restia goes gaga over them.
Est is an Innocent Fanservice Girl who doesn't bother to materialize clothes most of the time. However, she will always be wearing kneesocks, and becomes horribly embarrassed whenever some tries to remove them. Kamito calls her the "naked kneesocks spirit".
Greyworth: Hmph, this is my first time hearing something sincere from you without sarcasm.
Greyworth: Yeah, that's right. That mouth of yours keep saying rude things like witch or old hag.
Kamito: Unbelievable. How could someone say that to a beauty like you—
In episode 3, after waking up in Rinslet's bedroom, Kamito is understandably confused by seeing Est, a girl sleeping in his bed with him wearing nothing but knee socks. He has her hide under the sheets when Rinslet and Carol enter the room. After a while, Est moves under the sheet, prompting Rinslet to ask what's under there. Carol then mentions "That's what happens to men in the morning".
In episode 12, after defeating Velsaria, Ellis wears a fancy dress to the celebratory party. Kamito says it looks good on her, prompting a Clingy Jealous Girl reaction from Claire, Rinslet, and Fianna. All three girls push a piece of cake into his face, telling him to "eat their cake". But Est shoves an entire cake into his face, also telling him to eat her cake as well.
