Genuinely intriguing, MC gets transported into a game world where reanimated heroes of the past fight monsters at the direction of their summoners, much like in the Fate series. MC summons a supposedly low rarity hero who remembers nothing about himself and has to survive and grow in a world full of dangerous shadows and creatures. The summoned hero has a creepy yandere yibe at times too, often joking about how he's not that valuable and will be abandoned by MC once MC summons a better hero - but you can see the danger behind his words when he speaks. Thankfully, MC isn't an ungrateful ass so he's probably going to have a dangerous ML grow increasingly obsessed with him.
