Fairy Tail Wiki:Dragons of Design/Water Nest/6

Personality
As a dragon slayer, Natsu suffers from motion sickness. This ranges from anything that can be considered mobile to being carried by another person, except for Happy as he considers him family and not transportation. His sickness is at the degree wherein he can get sick by simply looking at a mode of transport or by just thinking about it. Despite being quite dense, Natsu is shown to be somewhat perceptive, especially when it comes to his friends and their feelings. After his battle with Gildarts during the S-class exam, Natsu has come to learn and understand true fear, and has already used it to help himself and his friends to grow. Prior to this event, only Erza’s wrath (albeit for comic relief), transportation and the Magic Council were the only things Natsu feared.

Personality
Ichiya is a womanizer like the rest of his group. Unlike them, he is nowhere near as handsome, though he thinks of himself as such. Regardless, the Trimens call him aniki (older brother) and show a great deal of respect for him. He and Erza Scarlet apparently have some history together, much to her disgust, and he constantly continues to hit on her. Ichiya is also as cowardly as he is vain, and usually prefers to run from a fight. However, there is a rare exception where he proves to be courageous by going against the Council to save Jellal Fernandes for Erza's sake. He is an ardent fan of perfumes. He has a habit of saying the English word "men" all the time, and he calls Erza "my honey" (also in English).
