luffy uses conqueror's haki for the first time

In a fanfic where Naruto uses haki, it could change his relationships with other characters too. For example, if he shows this new power, some characters might be in awe of him, while others might be jealous. His training to master haki could also lead to new interactions with mentors or allies who are familiar with this power. Also, his use of haki could potentially attract the attention of new enemies who are interested in this unique ability.

One possible storyline could be Naruto discovers he has Conqueror's Haki during a battle with a powerful enemy. This new power gives him an edge and he uses it to inspire his allies and intimidate his foes. For example, when facing the Akatsuki, his Haki could make some of the weaker members hesitate in their attacks.

In this kind of fanfiction, usually the plot might involve Luffy starting to discover his latent conqueror's haki power. Maybe he first experiences some intense battles where he unknowingly shows signs of it. Then, he might meet an old and wise character who recognizes this power in him and starts to guide him on how to control and use it effectively.

Aside from Luffy, characters like Ace might show up in this type of fanfiction. Ace, being Luffy's brother, could have some connection to Luffy's discovery of conquerer's haki, perhaps through memories or some form of spiritual guidance. Additionally, some powerful enemies might be present. These enemies would serve as the motivation for Luffy to quickly master the conqueror's haki in order to defeat them and protect his crew. There may also be some minor characters from the One Piece world who assist Luffy in his learning process, like the inhabitants of a special village that has knowledge about haki.

Naruto would become more confident. With Conqueror's Haki, he would know he has an extremely powerful ability. This would boost his self - assurance in battles and in his leadership role. For instance, when leading his team, he would be more assertive.
