He is often seen helping others even if it means taking a loss himself. He is logical, values order, and is very intelligent! He is also quite perceptive, possessing a high-level ability to judge what type of person someone is and what they want just from their actions. However, he rarely uses this for ill intent. He's a harmless kid who is incapable of being cunning or wicked. You can often see him eloquently talking his way out of situations even when someone tries to manipulate him. Being quite timid, he prefers safe methods and situations, but because he avoids anything that might harm his well-being, he sometimes takes somewhat extreme measures to prevent it. Usually, he tries to sacrifice himself rather than involve others. While this isn't a great way to handle things, he is quite stubborn about it, which is just heartbreaking.
