KO One: Losing My Memory from the Start

High school life was so bland and dull. Every day was exactly the same: waking up at six in the morning, eating three meals and washing up, attending the same classes, then having to go to bed around ten. I was nearly bored to death. Just when I was feeling fed up, the System appeared and brought me to KO One, a world I’d always longed to visit.

Storyline: KO One 1 → The X-Family → KO One 2 → KO One 3. The plot changes after that, and there won’t be many characters from seasons 4 and 5. The leads in KO One 1 and The X-Family both have amnesia. Later on, there will be more from the protagonist’s point of view.
