to get the obvious out of the way; hikaru has a crush on yuna. to my knowledge it isn’t outright stated anywhere, but the implications are there and they are heavy. yuna doesn’t reciprocate to the same degree, but she doesn’t pointedly not reciprocate, either. yuna is open to hikaru's affections and isn't shown to dislike or try to prevent hikaru from acting on them. there are quite a few moments where they are mutually affectionate with each other in a way they aren't with anybody else

adding on to that -- hikaru is wholly dedicated and devoted to yuna. her wish was to find something to become passionate about -- and that 'thing' ends up being yuna, as hikaru realizes in her magical girl story. hikaru's devotion to yuna is something that takes over a major part of her life and affects much of what she does and how she does things. there are moments when hikaru vehemently reinforces and insists that she is dedicated to yuna and yuna alone. in crimson resolve, hikaru refuses to leave yuna's side even for her own safety, declaring that yuna is 'all hers', and so doesn't have a say in whether hikaru leaves or not. there is so much that can be said about hikaru's loyalty to yuna -- i could probably make a whole post talking about it by itself. bottom line, it's all-encompassing, and a big part of hikaru's character

hikaru's devotion and feelings for yuna are shown in her doppel quote -- her cry of 'don't take her away from me…!'; hikaru's despair is the thought of yuna being taken away from her

hikaru and yuna know each other better than the other promised blood members, and have known each other the longest -- since before the bloody tragedy and any of the events in futatsugi took place. as mentioned, there are multiple moments where it is shown and mentioned that they are uniquely affectionate with each other in ways they are not with any of the other characters (handkerchief scene, yuna fixing hikaru's uniform button, etc.). which leads me to --

-- in the beginning chapters of arc 2, hikaru can calm down an enraged yuna and bring her back to her senses. when yuna's burning thirst for vengeance clouds her mind and her logic, and she resorts to pure emotion and instinct, hikaru can pull her from the depths of her rage and pacify her. and quite easily, too. (see; arc 2 chapter 1, 'you're getting too heated, yuna.' / 'hikaru…')

lastly, and i intentionally saved this for the end (it's what got me into shipping them); their promise to die together, no matter what happens. in crimson resolve, when yuna is sending away all the members of torayamachi to join ryuugasaki for their own safety, hikaru stays. hikaru stays, claims that yuna is 'all hers' and so she has no say in if hikaru leaves. yuna says it's cruel, to herself, to her family, to everybody. to which hikaru responds by saying that if she dies, she will be waiting for yuna in hell. and that if yuna dies, she will follow her. with a content smile, yuna asks if they shall walk down the path to the land of the dead together

in the bad end version of this scene, hikaru even says that if she joins ryuugasaki, she'll lose the most important thing in her life. no -- she will lose her life itself. ('that's why…yuna…you're my life.') yuna says it's touching, but cruel, and that people will be devastated if hikaru dies. hikaru says she'll be doomed to turn into a witch if yuna dies, anyway, and they make that same promise to die together

there are countless other, smaller scenes and exchanges between them or them and other characters that reinforce these ideas or otherwise fuel the ship --

hikaru embracing yuna to soothe her and prevent her from killing juri at the end of crimson resolve. yuna's speech toward the beginning of crimson resolve describing hikaru so gallantly, so confident in hikaru's abilities. hikaru insisting that she 'isn't interested in anybody but yuna.' hikaru whining about how if she 'doesn't experience yuna's affection soon' when forced to be separated from her for one of promised blood's plans. hikaru gets jealous over dogs for getting more praise from yuna, and then tries to prove to yuna that she's better than those dogs. there's even the end of hikaru's magical girl story, where yuna teases hikaru with the idea of a rumor about them circulating if people find out hikaru has yuna's handkerchief (and gives it to her anyway).
