Graylu is the Het ship between Gray fullbuster and and Lucy Heartfilia from the Fairy Tail fandom.

Canon
Lucy and Gray are great friends and members of the same team. Gray cares much for Lucy, going as far as to say that he would rather die than hand Lucy over to Phantom Lord (During the Phantom Lord arc). In return, Lucy is usually annoyed by Gray's stripping habit and his tendency to break into her house without his clothes, which Lucy has scolded him about and beat him for. However, Lucy is greatly amazed by Gray's skills and cares for him. According to Gemini, who not only copies one's looks and abilities but also one's thoughts by Copy Magic, Gray's opinions about Lucy is as follows: In Erza's “funeral” dream, while everyone was at her funeral, Lucy was seen crying and shouting at Natsu while gray ran over to Lucy and tried to comfort her by hugging her.
 * Newcomer to the guild.
 * Looks pretty damn cute.
 * Possesses some skill.
 * More naive than she appears to be.
 * A Celestial Spirit Mage.
 * Somewhat interested in her (anime). Pretty damn cute (manga).

Edolas arc
During their fight with Sugarboy and Mary Hughes, Sugarboy traps both Gray and Lucy by making the ground soft, sinking them waist-deep. Gray then uses his strength to throw Lucy.

In the Manga, Lucy tried to rewrite the book of E.N.D, while she was rewriting it, the book started burning her with Natsu’s flames, Gray grabbed her and he sacrificed the last of his Demon slayer magic just to save her.

X791 Arc
As the middle of training happens, Virgo suddenly appears and told them to come; Lucy and Gray come to the Celestial World with Natsu, Juvia, Wendy, Erza, Happy and Carla. After some events, Gray is seen patting Lucy as they sit down, playing with the Canis Minors.

Tower of heaven arc
As they are looking for Erza, Natsu, Gray, Lucy and Juvia stop to eat in a dining area in the Tower of Heaven. Virgo (who was already summoned) suggests that Lucy changes out of her bikini. As she helps her change, Gray looks over very surprised and he blushes. After, Lucy asks the boys how she looks and Gray agrees that she looks good in her dress. Virgo even includes the comment "He loves her!" just as Happy would.
