Not sure. When I was young, I dreamed about becoming a mangaka, and I’d drawn quite a lot of them. Now they’re nowhere to be found—maybe somewhere in the storage room.
I don’t know what my oldest story is, but I vaguely remember the first time I drew manga, it was a straight up One Piece ripped-off. It was about a guy who goes on an adventure, becomes a pirate, gathers crews, acquires a ship, goes on an island in the sky—sounds familiar? As far as I remember, that must be the first story I’ve ever written—or drawn, if you will.
Then, I vaguely remember stories about a mad scientist with lots of crazy gadgets, a guy getting isekaied into another dimension and becoming its ruler (I didn’t even know about isekai at that time. It all came from me), Stone Age community with strange techs and supernatural powers, a badass hunter roaming the world full of dangerous monsters. (There are more, but that’s as far as I can remember.)
All of them are highly dream-like—which is another word for “doesn’t-make-much-sense.” But when I drew those mangas, I was like in elementary school or something. Those were good old memories.
