失われたエン

Flirting

Natsu is a big flirt like loke and he knows how to make women fall for him. His body is one reason most girls find him attractive at first. His charm, sweet tone and the way his eyes stays on the person he is talking to will close the deal so he can do anything he wants with the girl/boy without them even complaining.

Natsu can be alittle shit at times. He has a very bad side that comes up only when he wants to be playful or do some terrible things like hurting people. He doesn't hurt people unless it's sexual which then his behaviour is out the window and he is just like a beast which is good when he is fighting since he doesn't need to think much when he fights.

When Natsu is in Love

To everyone in the guild fairy tail they would guess that Natsu hasn't got a clue on what love is but to everyone's surprise he knows a great deal about this subject as he observed others that where in love and Igneel was telling him about his and explain a fair amount of the subject to the dragon slayer.

When Natsu falls in love with someone he truly does fall inlove. He may be alittle new to show others how he feels without using his fist to protect them but he will show the person he cares about with love to make sure they understood how he feels. He wont change his behaviour much to those he has fallen for they'll see a different side to him that he wouldn't let anyone else see which is allowing the person to see the true him instead of the one that protects those he cares for.

Good points

He is loyal to the person he is with

Protect them no matter what the cost

Will stay by there side no matter what

Truly loves them, supports them, respects them

Exercise

In the care of Igneel, Natsu use to wake up at dawn and began training with his father. Every day he did several hours of training with the dragon from his fire magic down to working out so his body could get stronger to handle the magic he has inside of him.
