So... .basically, Poseidon is Gilgamesh (fate) of this universe that is always looking down on his opponent until the end and don't end things when he has a chance until it's too late (Kojiro would be Emiya since he cuts Poseidon arms off too lol). The first 2 fights for those 2 gods "at least"...
@ninjadork Well . . . the story wise is pretty interesting to me so i'm gonna stick with this for a while ( since i don't mind about the genre as long as it has good story :D ). The character relationship wise is not that bad if you ignore some part you don't like. but . . . after all it...
This is just my assumption from someone that don't read the novel version. My guess is his "core power" is more appropriate to be something like "Delete" than "Instant Kill" . Since killing mean to make something "not alive" . If we consider his power as "Delete" then even the power of "Concept"...
@cloud04 it said in the novel version that he only has to think of killing them is enough to use his power. The reason he say it out loud is just because it's easier to pinpoint the target than just thinking them in his head.
