HiyoIku

HiyoIku is the slash ship between Hiyori Tono and Ikuya Kirishima from the Free! fandom.

Dive to the Future
SPROUTING DIVE START!

Hiyori and Ikuya are on a bus when Ikuya accidently voices out loud that he’ll never be ordinary. Hiyori tells him that being ordinary isn’t something he should have to worry about, since he’s Ikuya. Ikuya asks if that’s meant to be a compliment. Hiyori says yes, but then asks if he made the other boy mad. Ikuya says no, and stares out the window.

A PROMISE ON A SHOOTING STAR!

After the race, Ikuya is in the shower, when Hiyori startles him. Hiyori wants to take off, but Ikuya really doesn’t understand why, since there are still other races. Hiyori says that there's are finished, so they can leave. He asks if he wants something to eat, and he’ll let everyone else know that they’re leaving. They then go to a restraunt, where Ikuya asks if Hiyori’s backstroke time improved. Hiyori says it has, but it’s not as good as his, and then tells him to let his brother know about his race today. Ikuya says that he’s not in a rush since the he’s in another time zone. He then observes how weird Hiyori is acting, but Hiyori responds that he’s always weird.

As they head to the train station, Ikuya realizes he left his phone back at the restaurant. He says that he’ll see Hiyori tomorrow, which seems to disappoint Hiyori. Hiyori eventually follows him and find him talking to Haru. Ikuya asks why Hiyori didn’t head home already, and Hiyori says he got curious. He quickly acknowledges Haru before telling him that Ikuya is tired from his race and he should take him home. He then starts to lead Ikuya away.

Fanon
Shipping between the two started after the release of Timeless Medley, but took off more after the release of Dive to the Future. Many shippers liken Hiyori to a jealous or overprotective boyfriend, given his manipulations to stop Ikuya's friends from middle from seeing him, and his reminders to Ikuya to take care of himself and call his brother. Shippers are also drawn to the seeming pride Hiyori has over Ikuya, given the former's need to compliment Ikuya all the time.
