According to me I think that Kai do Amore Hilary and she too I can prove my point da several reason :-
1) When they met in the 6th episode of V-force Hilary detto to Tyson to introduce her to Kai.
2) When for the first time they meet Kai was quite which he does never means he want to know about her.
3) When Hilary saw the foto of Kai she say him cute.
4) When every one was against Hilary and Tyson tore the page Kai was only one who supported her and accept in his team.
5) In the episode 15th of V-force whe nobody was mostrare her their big-beast she begged every one but touched Kai only.
6) Normally if anyone touches Kai he reacts but he detto nothing to her.
7) When they were in the evil island of Dr B they decided to diviso, spalato but Kai detto that he want to go with Hilary and Kenny as they need his protection.
8) And when the stone was falling down Kai warn them and protected hilary only and shielded her and she was blushing.
9) When the Kai was fighting with Figel and he was losing Hilary was continous saying Kenny to help him and after Kai won the words of Hilary were "Who's the man,Who's the man,Kai is the man,Kai is the man" which shows her happiness.
10) And the one thing that I noticed in all the episode was they are always walking together.
11) When Hilary is not able to understand any thing Kai always explains her.
12) When Kai is in the battle the only one who is worry and cheering is Hilary only which she does for no one.
13) When in V-force when Kai was going was left the team when Hilary detto that he should not leave team he follow her and don't left the team.
14) When in G-Revolution Kai was fighting against Daichi and he was loosing Hilary detto to Tyson and Kenny that he might want to leave the team and when she was saying this she had tears in her eyes.
15) And many più reason for it.
