So far almost all the screen time has been spent with our main quartet, Laios, Chilchuck, Marcille and Senshi.
We met some orcs, and Kabru's party has had two short minisodes. Farlin has also been around in flashbacks. But aside from that, the cast is still quite small.
The OP teases that the eventual character count will rise well past two dozen, but I though it might be fun to facilitate some discussions based on what we've seen of the main group so far, before the next episode introduces several more significant members of the cast.
Tough question. In ensemble shows like this, it can vary for me depending on the story/episode. If I had to pick a character that I have been enjoying the most, it is probably Marcille. Between how expressively she is drawn and the great VA work to go alongside, it has been great.
I think the character that I am most interested in is Laios. He can be really weird sometimes. He has a tendency to kind of forget what he is doing or get easily sidetracked or off on some tangent. You could see this all the way back in episode 1 when he was busy thinking about how hungry he was instead of focusing on the fight with the dragon. Similarly, this has happened in a couple other fights they have had, where Laios is kind of standing around, thinking about some nonsense while his party continues to fight. This tendency to go off on tangents (often monster food-related), is at odds with what should be a high priority for him, saving his sister. I just feel like there is more to Laios that we haven't really seen yet. Or....maybe he is just kinda weird that way.
I have seen people elsewhere online compare Laios to being neurodivergent. I don't really have much firsthand experience with neurodivergence, so I can't really speak to the comparison. However, I do find it interesting that people are connecting to an anime character in that way.
