Ooohh, I'll give it a shot and test to see whether my characters are actually likeable.
Name: Kuro Sylphias (The Main MC)
Visual: His hair color is originally silver, but true to his name and circumstances, he had to dye his hair black since the color silver means evil in their world. He's fairly short for his age (5'2") and he's healthily fit, even slightly possessing abs. He usually wears simple outfits, since in his past life he was an introvert, so his clothes aren't really good-looking at all, especially since he possesses the normal look, neither handsome or hot nor is he ugly.
Description: He's... Shameless at times. He WILL rant when he wants to rant, when he's bored, he WILL show it, when he's sleepy, he WILL show it. He's also lazy most of the time, being an introverted guy, he always sat in front of his pc in his past life. In his current life, he likes to explore the green world, free from all the worrying things of current modern world. Shameless, lazy, immature, he's also jerkish at times, but when he finds out that his loved ones are in trouble, he will never hesitate to give his own life to save them. He won't involve others in saving them, claiming that his life will be the only thing worth theirs. He's kind too, being kind to children and taking care of them when the kids want him to do so themselves.
Name: Gran Mercse(Mercy)
Visual: His hair color, true to his abilities and race (Gale Dragonkin), is light green. He's a bit thinner than Kuro, and is a bit taller than him (5'4"). He usually wears clothing that mostly covers his body, due to the fact that his weapons surround his body and are released when he chooses to do so.
Description: In the current early years, he's a chuunibyou, being known to act cool several times. Well, his ability let's him release all his weapons, which are guns made by Kuro, and shoot them all around him while controlling all the bullets. Though he acts cool, he's very weak to compliments. He's also very kind, a lot sweeter than Kuro in general and is a bit aggressive when it comes to girls. Upon growing older, he becomes more serious and level-headed while keeping his "cool guy" persona. Due to mysterious reasons though, he's obsessive when it comes to protecting Kuro.
Name: Kenny Rockbourne
Visual: He has brown hair due to his race (Earth Dragonkin). He's a lot bulkier than Kuro, and is very big at his age (5'9.5"). Because of this, he wears adults' clothes. His weapons are just his fists, which dons gauntlets.
Description: He's that one wholesome guy in the group, and unlike the others, is the most mature in the group. His patience is also commendable, being able to take insults like it was an everyday snack and laughing at it. He's like Braum from league of legends basically, big and wholesome. He's that one guy who will listen to all your problems and will help you out to solve them. Just like Gran, he's also obsessive when it comes to protecting Kuro.
So uhh, what do you think?
