Koneko Toujou/Relationships

Issei Hyoudou
At the beginning of the series, Koneko disliked Issei because of his perverted and lecherous nature. In Volume 5, Koneko started to develop feelings of love for him after Issei helped her overcome her fears of using Senjutsu because Issei told her that he would stop her if she ever went out of control. Koneko's feelings for Issei kept growing until it reached its pinnacle when it forced her into mating season and chose him as her partner. She was snapped back to normal by Kuroka and she proposed to Issei to be his bride in Volume 11, which Issei accepts under the condition that she grows bigger. She wants to be more than just a girlfriend to Issei because she chose him to be her soulmate. Her relationship with him is very serious but she will have to wait to develop more because her body is small and it would be a danger to her to have children at this point.

Rias Gremory
Koneko is very loyal to Rias and cares a lot for her after Rias took her in and helped her get out of her depression after her sister, Kuroka, abandoned her.

Ravel Phenex
Koneko has a love/hate relationship because she is a Nekomata and Ravel is a phoenix (alluding to the natural rivalry between cats and birds). She has a rivalry with her because she is in love with Issei and Ravel is also competing for his affections. However, there are times in which they do get along because Ravel doesn't really hate Koneko. In Volume 14, the two are shown to be fighting over the spot on Issei's lap.

Yuuto Kiba
The two appear to have a positive relationship, as in Volume 3, Koneko was willing to disobey Rias's orders to help him find closure with the events of his past. Koneko sees Kiba more as a brother and even stated in Volume 3 of the light novels that she would "get lonely" if Kiba disappears, this would mean that Koneko really cares about Kiba.

Kuroka
She cares for her sister but she is angry at her for what she did to her old master even though she was right for doing this. Koneko had to live a tough life because of her but Kuroka loves her greatly, and Kuroka proved it when the Hero Faction attacked and she took a hit for Koneko. Issei told Koneko that she is a good person, although a "naughty cat", and is willing to punish her if she did anything funny to Koneko. Koneko is thinking about re-establishing her relationship with her and thanks Issei for the courage he gave her.
