Maka Allbarn in Danmachi with Shinigami Powers

Maka Akabane > Soul Eater
A Death Weapon Meisner, student of the Death Weapon Meinsner Academy (who's principal is the Grimm Reaper himfreakingself mind you) and one of the anime's protagonists. The academy trains both demon weapons(humans who can shapeshift into weapons such as swords, guns, spears, etc) and their meinsners(the ones who wield those weapons and power them with energy from their own souls). The academy's staff and studends alike are the worlds police, hunting evil people and taking their souls to feed the demon weapons(AUTOR NOTE: remind me not to be a bad guy in that universe*shiver*). They also give the good souls that the baddies have the tendency to steal, back to the Grimm Reaper(AUTOR NOTE: so the Reaper can guide them to the afterlife i assume).

Shinigamy powers > Bleach
Shinigamis guide the good souls of the dead to the afterlife(that they also manage and protect) and purge the evil ones. They use the energy from their souls to cast spells known as demon arts, the spell does require chants but skilled casters can shorten or even compleatly forgo the chant to cast the spell with diminished returns. Shinigamis all have their own unique zanpaktos, that are sentient weapons created by their souls, a shinigami's zampakto is their eternal partner in their extremely long lifes. There are rare shinigamis that can tap into the power of the evil souls ,known as hollows, that they hunt, those shinigamis are known as vizard.
