Despite his appearance, Kaiman is a very cheerful character. He is like the mascot of the anime, even in the most desperate situations, he manages to entertain both himself and the viewers. But at the same time, when events come to the most serious point, he gets serious too and shows his fighting skills. On the other hand, Kaiman's best friend Nikaido is a more serious character than him. She is even more skilled fighter than Kaiman and has a very complicated backstory, but since this is a non-spoiler review I won't talk about it. But trust me, her backstory is really interesting.
Apart from Kaiman and Nikado, our other main characters are En Family, consisting of five people: En, Shin, Noi, Fujita and Ebisu. We meet with Fujita in the first scene of the anime when he and his partner fighting against our main duo. During this fight his partner dies, but before he dies, he opens a door to magic users' world and saves Fujita. After his partner's death, Fujita asks to En for help in revenge from Kaiman and Nikaido. In the following parts he meets Ebisu, who by chance falls into Kaiman's hands in Hole. After a short fight he saves Ebisu from Kaiman. Just like Kaiman, Ebisu is a character that we can count as the mascot of the Dorohedoro. In her fight with Kaiman, she loses all the skin on her face and (although her face is healed) she is slightly become a lunatic. Then we have fun while watching the funny things she does in this lunatic state.
Shin and Noi are partners working under En's order. This duo are the my favorite characters of Dorohedoro. Because they have a great harmony and their every scene has a perfect blend of comedy and action. Also their background stories are pretty well-written. Shin's background story reveals the bad aspects of Hole, showing how rotten both sides of Dorohedoro's world. Noi's background story shows although the things that she does are malicious, how kind hearted and unselfish the character is. In short, in Dorohedoro's world there are no characters who are absolute good or absolute evil, all the characters are in shades of gray, like the atmosphere that anime has.
Give this adaption a try as it's sure to pass time & fingers crossed for season two to come quickly!
