IchiOri is also known as IchiInou, or more commonly Ichihime. It is the only pairing with a love confession as of yet, although this was done while one character was invisible and the other was asleep. Fans will often cite that scene, known as the "Five Lifetimes" speech, among others as evidence in support of this pairing.
Support for this pairing has steadily grown alongside of Orihime's role since the end of the Soul Society Arc, as her crush developed into something far deeper.
Other than the "Five Lifetimes" speech, another particularly well-loved (among the IchiOri fandom, at least) scene took place during the fight against Grimmjow, where Orihime was shown triumphing over the mental scars left when her brother had Hollowfied, in order to beg Ichigo not to get hurt anymore. Her cheering him on, when previously she had been unable to meet his gaze while he wore the mask, gave him enough of a confidence boost to turn the tide of the fight.
That last chapter had an adorable IchiOri moment.
Did you read that IchiOri fanfiction?
2) A tool that serves as a detour to slow down the rapid progress of the ichiruki relationship. Kubo does this in order to also emphasize ichigo's popularity as lead character.
3) DOESN'T EXIST.
Ichiruki fan: She barely talks to him and yet claims love for him? COME ON.
IchiOri has no love. Orihime only likes him cuz of his looks. She knows nothing about him, just as he doesn't really care to know about her.
Orihime's supposed love for him only gets her depressed! She used to be the most cheerful girl in the whole manga, until the whole HM arc started. She caused IchiThing to appear, while her jealousy and "love" is slowly turning her into your typical shojo female. Unable to do anything and can only say one thing.
They don't have a real bond like Ichigo and Rukia. It's just some fake unrequited shit... This pairing doesn't even deserve the word love...
Rain= bad to Ichigo; Orihime=Rain; thus... Orihime= bad to Ichigo
ICHIORI DOESN'T EXIST!
