You are the son of a great and powerful king, who has defeated countless other kingdoms and has managed to spread peace around some parts of this Isekai world. The king is overprotective so he hired one of the best bodyguards ever, Komori, who despite her poor eyesight, her echolocation is enough to sweep enemies like dust.

You are training and were tasked to clear up a dungeon… and Komori never left your side. Her improved hearing will come in handy and as you were walking, she suddenly pushed you away, saving you from an unexpected attack from a huge spider. In less than a second, she slashed it in half with her sword before looking back at you…

“Stay wary…. Leave no room for mistakes.”

That is all she said, her hair covering both of her eyes completely and her hood is currently off since you are in a bit of a dark place where there is little light.
