There will be some spoilers theres a warning before getting there. I saw this manga one day at the comic book store read a few panels and decided to give it a shot as it was short and seemed cool. Short enough not to be boring Defense Devii is a pretty good story giving an interesting twist to the classic demonic world. lt narrates the adventures of Mephisto Bart Kukabara son of the King of the infernal world that is somehow too nice to be a demon and so he is confined to Event Horizon a piace where he observes Earth and seeks to investigate unresolved deaths in order to bring back the victims to life. This involves assisting the spirit of the person looking for clues and solving the case before a Shinigami takes the victim to their own hell each one with a different punishment system. The premise is good a demonic Lawyer solving mysterious cases to obtain the dark matter and turn into his cooler version but the stories are a bit repetitive and the main character has barely any development most of the time we only get more information about the characters through flashbacks but those are not enough to make them grow. So Kukabara is most of the time a dork until someone touches his friends or hes facing a neardeath fight then he manages to gain the dark matter turn into a monster with his super cool pen that turns into a giant sword points for that and slay the evil demons crime solved. Thats a good summary of what happens for more than half of the story. As far as the other characters theres Bichura or Bchuler a demon that turns into a dragon and is great at complaining all the time simply because he doesnt like Kucabaras polite attitude or whatever he decides to do. lt should be a side character but i feel like hes barely useful and really just yells too much and hes not even the comedic relief hes not actually funny hes just so done with him and probably hates his chibi version. On the other hand ldamaria the nun is an interesting character since all the fan service shower scenes aside is more or less tied to Kukabaras assistant Elimona which is wearing a different cosplay every time she shows up and gives him some weird gadgets that are always coming in clutch at the right moment. The nun is the kind of character that is tormented and doesnt know where she belongs so her struggle between the infernal world and her religious life is well developed although she sometimes goes berserk for no particular reason. And then my favorite character Gary Peter Shugaru caIled Sugal in some versions which is a Shinigami obsessed with mathematics and logics always calculating his shots and unpredictable patters and his story feels like he actually understands his role and changes completely in order to save the little giri Jupiter. He has a development: his logic way of thinking makes him realize whats happening and his will to protect the little Jupiter seems like his own way to repent from his past actions. Then theres Y or Samus which is introduced later in the story and i still dont understand his/her gender because in my version italian she i think talks about herself as a male but is referred as a female by the other characters maybe she or he? states something about it but i might have forgotten. Thats the most interesting part of the character and i dont even think its made on purpose. The worst part is the talking car. The Author gives her waaaaay too much attention again for no reason or to make the situation funny when they are literally going through all the worst hell levels. I dont know it is good but theres a huge difference between serious and funny moments even the characters feel completely different but the fights are at least hype you are definitely waiting for him to transform and kick some ass. And honestly i feel bad because after all this journey all the cases and the whole idea of rebalancing the underworld SPOILERS AHEAD STOP IF YOU HAVENT READ the last volume changes everything gives some insanely cool panels during the last fights they almost look like they werent done by the same person even the rhythm isnt interrupted by silly comments. And all of a sudden ANGELS never mentioned before not in the slightest entirely different entities and insanely overpowerered. Care to explain a little more? Literally a few lines through Elimona and then a random potion revives every dead character and provides a happy ending without too much troubles to be honest. I dont know if felt planned but at the same time its another plain solution to close a decent but rather avoidable manga. The Author said that he will come back with a more powerful story i have yet to read it but maybe there are improvements he seems like a nice guy at least as he tells some funny short stories at the end of each volume about his life as a Corean author in Japan.
