Link is anything but normal.

Zelda had little to act on to believe that Ghirahim was not the only surviving member of the race, beside the bokoblins he now fought alongside Link to destroy, and Zelda is unsure of the idea that Ghirahim has been left alive (GhiraLink oneshot, Zelda's POV)

Ghirahim fights against Link again, although this hero is not the one he remembers. (Onesided GhiraLink, if you squint. Was in Skyward Sword's category before the games release. Also was written when all there was on their interaction in game was a few screenshots. Written before even Japanese release.)

Roy's blinded. He needs his light, but someone has a conversation to hold with him. (RoyEd, during and post Promised Day)

Link's eyes were wary, shifting around the space. Time seemed to pass by slowly, and the very bane of her existence was just going to make her life a little worse. And to make it more of an eternal hell, they have to fight together, if they don't end each other first. (Genderswap Link, intersex Ghirahim, GhiraLink)

Ghirahim longed to find the demon, yet he wasn't sure about what he felt about the situation of Link, and yet, the demon was one that had many things in surprise for the hero. (LinkGhira, roleswap AU)

Fate was a cruel mistress. She loves her tapestries and she loves her hero and demon.

Ghirahim contemplates his relationship with Link after he brings him to his home. (Inspired by art by Raven-Igma on deviantArt)
