Merlin

A young man who is like a wind blowing on the grasslands. Before him, anyone would end up letting the tension out of their shoulders - a refreshingly righteous person. Still, due to seemingly being quite lacking in terms of seriousness and such together with a lack of the sense of responsibility, one can see that Merlin may also appear as a shady con man. A rhetorician who, even while perceiving things in an objective manner and accepting the cruelty of the world of humans, turns it into something bright by saying things like: “But, it wouldn’t be fun otherwise, right?

Despite being a hybrid being, Merlin has never hated humans. Rather, he is fond of them to such a degree that it is beyond natural. He loves the world of humans, loves mischief, and loves girls. Generally, he is the Magus of Flowers who retorts at most things with a refreshing smile and a calm expression such as “now, now.”

He claim's his emotions are generated from human dreams, he has none of his own. He doesn't believe he is able to love anyone, he only loves the concept of beauty. Beautiful stories, Beautiful emotions, beautiful women a beautiful happy end for humanity. He openly admits to leech his Masters emotions, but seems still to care for her.

Openly like this, he tends to appear as having a perfectly happy personality, a perfectly happy guy, without a single worry, but since Merlin himself is self-aware about the fact that he is a foreign body in regards to human society, he never crosses that last step... the wall called friendship. Ultimately, (just like a child who enjoys tasty food,) he is always watching over and protecting the world so that mankind can reach a happy outcome.

... So, if one is looking only at the end result, Merlin is a good man, and a wise one. But inside, he is an incubus, a being very far apart from humans. He, a being that consume dreams, can essentially understand human emotions, but cannot truly sympathize with it. He is an alien-like, inhuman being, who only rationally excuses himself inside a dream (dream = a human mind activity) and consumes it, and then leaves just like an insect. Merlin is very boastful about his abilities as a mage, claiming that he inflicts jealousy and envy on all other Servants, especially Casters, since they are second-rate to him.
