Here are my favorite picks for anime like Blood Lad. Keep in my the list is in no particular order. Enjoy the recommendations!
Set in the Shinigami technical school for weapon meisters. The series revolves around 3 groups, each consisting of a weapon meister and a human weapon. Trying to make the latter a “Death Scythe,” which is the highest title for a weapon and thus fit for use by the Shinigami, they must collect the souls of 99 evil humans and 1 witch.
Soul Eater revolves around Maka & Soul Eater, Black Star & Tsubaki, and Death the Kid with Patty and Liz Thompson. Besides taking the time to gather souls, these students of Shibusen defend Death City from some of the most powerful of creatures while still attending school and trying to become stronger.
In times of need, if you look in the right place, you just may see a strange telephone number scrawled in red. If you call this number, you will hear a young man introduce himself as the Yato God.
Yato is a minor deity and a self-proclaimed “Delivery God,” who dreams of having millions of worshippers. Without a single shrine dedicated to his name, however, his goals are far from being realized. He spends his days doing odd jobs for five yen apiece, until his weapon partner becomes fed up with her useless master and deserts him.
Just as things seem to be looking grim for the god, his fortune changes when a middle school girl, Hiyori Iki, supposedly saves Yato from a car accident, taking the hit for him. Remarkably, she survives, but the event has caused her soul to become loose and hence able to leave her body. Hiyori demands that Yato return her to normal, but upon learning that he needs a new partner to do so, reluctantly agrees to help him find one. And with Hiyori’s help, Yato’s luck may finally be turning around. [Written by MAL Rewrite]
Devil King Sadao is only one step away from conquering the world when he is beaten by Hero Emilia and forced to drift to the other world: modern-day Tokyo. As “conquering the world” are the only skills the Devil King possesses—and are obviously unnecessary in his new situation—he must work as a freeter to pay for his living expenses!
Humans and demons are two sides of the same coin, as are Assiah and Gehenna, their respective worlds. The only way to travel between the realms is by the means of possession, like in ghost stories. However, Satan, the ruler of Gehenna, cannot find a suitable host to possess and therefore, remains imprisoned in his world. In a desperate attempt to conquer Assiah, he sends his son instead, intending for him to eventually grow into a vessel capable of possession by the demon king.
Ao no Exorcist follows Rin Okumura who appears to be an ordinary, somewhat troublesome teenager—that is until one day he is ambushed by demons. His world turns upside down when he discovers that he is in fact the very son of Satan and that his demon father wishes for him to return so they can conquer Assiah together. Not wanting to join the king of Gehenna, Rin decides to begin training to become an exorcist so that he can fight to defend Assiah alongside his brother Yukio. [Written by MAL Rewrite]
