The amount of characters in Jormungand to talk about is quite over whelming, so I'm going to go out on a limb here and just covering the ones I feel are the most notable and important in this series. Jormungand's characters are all somewhat simple, although Jormungand is a series that spans 2 seasons and being 8+ hours, the division of screen time between characters and the commitment to them seems a bit stretched overall.If Jormungand suffers from anything, upon closer inspection it's the somewhat bare bones characters, I honestly really don't have much to say about the rest of the cast, as the amount of given subject material regarding most characters simply isn't substantial enough for a compelling conversation - However Jormungand is a story that has shown that it doesn't need deep character story or a complex narrative to still be entertaining. I feel actions in this case, speak a bit louder than words, even if the primary action taking place are Gun Fu Fights or simpler tales on the battlefield. A good example would be Velmet, as her story is somewhat bare bones and simplistic being a tale of revenge and blood lust.
I do however like Velmet's role in her relationship with Koko and how she supports her, particularly in her younger years, when Koko was just making her debut in the arms trade. In Koko's words, Velmet is something of a mentor and teacher for her, being supportive as a friend as well, being that Velmet is older, and has more battlefield experience. Throughout the story, when Koko is feeling low or when she breaks down, Velmet serves as her backbone to bail her out of those situations. Despite being a frighteningly violent and knife happy character, she does offer "service" by fawning over Koko. Lehm Brick plays a similar role, although in addition to serving as something like an adviser to Koko, he also watches over Jonah in particular, being somewhat of a leader as well, being second in command to Koko.
Jonah, slowly but surely grows to like his comrades and Koko, perhaps viewing them more and more as something like a family, all of which share their own tales on the battlefield as they travel across the world together as nomads. Koko herself dawns an iron mask with a smile, fawning and falling all over Jonah like a puppy, always pushing herself to be amicable and energetic. Though Jonah soon begins to question himself and Koko as she reveals a the colder side of herself and how black her heart her heart is actually becoming. If anything though, we begin to realize that, despite Koko acknowledging that she's becoming a monster - That too is perhaps her lying to herself to who she is as a person, being that in the end, we discover she's just another girl, with same emotions and feelings any girl her age would have, that she perhaps has tried to abandon. This is touched upon a little bit, though sadly wasn't really explored much farther.
Perhaps in a addition to Jonah, another character we could level with more could have been introduced, though I digress, since I still believe a character as vital to the story as Koko is, that she could have fulfilled this roll. Being that, in the anime we do we receive flashbacks of Koko when she was younger, less mature and more of a fragile young girl than anything else, along with other moments where Koko seemingly brakes down. Being so heavily involved and having so much blood on her hands, what Jonah means to Koko is perhaps shown in his youth as a child soldier. She believes that one day, while taking a child into her life that she can perhaps throw it all away one day and abandon the underworld for a normal life, Jonah represents that. She fears herself and what she's becoming, and she's deeply afraid of her comrades abandoning her after seeing her actual self, she's deeply afraid of Jonah leaving. Though, throughout the story she continues go deeper and deeper into the underworld, staining herself with blood on her hands, while using the money and power she gains from it, to fight for a different alternative, to justify herself and her flaws as person. I feel her personal story could have been expanded upon a little more, though that decision is something that Manga artist and author Keitaro Takahashi should have made.
Jormungand is a story that does somewhat revolves around Jonah and Koko, as Koko amasses her influence and power across the world as she's devilishly cunning, persuasive and charismatic enough to negotiate and put others beneath her thumb. This could perhaps be due to the rest of the characters not having much of a story or complexity as a character. it's more or less the same across the entire board. Though many characters such as Velmet, Chequita and Karen Lo all make up for their simplistic character stories or lack thereof by showing their personality and character by being bad ass, and having comical dialogue. It doesn't bother me to much, because again, being that most of our character are adults, most of them have their lives sorted out more or less, and don't have some problem, personal flaw or ambition they need to resolve, and I'm somewhat fine with that, because the characters in Jormunagnd may not have much complexity or depth in terms of their backgrounds and past, though to compensate they establish their presence as comrades that can rely upon each other, compensating a lack of character depth with style and flair, and their proficiency to kill, in which case the characters of Jormunagand succeed in keeping the series lively and fresh.
