Light hair, sometimes ponytail, round glasses

I want to take some time to talk about this character archetype in anime/manga I see often, and I also enjoy lol. Here's some examples of what they look like (more examples to come):

An image of Kaien from the anime Vampire Knight an image of soubi from loveless An image of abel from trinity blood Johann from Vanitas no Carte

These light hair, sometimes ponytail, round glasses are characters who are able to look and act distinguished at times, but usually come off as goofy comic relief. Adding comedy to series, while also having depth to themselves aside from their jokes.
