It starts off well, but becomes very bad thereafter. By the end of the season, it's a total mess. The last two or three episodes feel rushed.
The protagonist has no identity to call his own. There is zero mention of his past life and in this world, he uses abilities of a buff warrior/ tank, can use white magic such as healing/resurrection, has spells of black mages such as fire/ thunder, and can also summon monsters from another world. The side characters aren't even surprised enough in the end. They just call him 'flashy', when tbh, they should be down on their knees after experiencing this much power.
Same themes of slavery and abuse repeats itself again and again. Same allies conveniently show up in every fight. It becomes so laughably bad that someone gives the MCs directions on where to go for their quest and then themselves shows up at the location to fight with them.
The politics is childish, and the antagonists act really foolish in the last few episodes. They are hyped by cool names, but do not deliver as expected.
