Rubo Mirukawa
Hello reader,
If you're reading this bio it's either because:
a) you like knowing things which means you're in the right place or
b) you're me from the future or Hikaru and this isn't your first time here.
Regardless of which cohort you're from, I'm glad you're here because there's something I've got to get off my chest, reader. I'm a light novelist for readers who like to feel trusted and I write about isekai, rom-com, slice of life, fantasy, and supernatural fiction.
Genre, as I see it, is not a set of rules; it's a suggestion. Whether the current muse is a piece of music, character, or joke that refuses to leave my head, I'll probably make up a whole thing about it. Sometimes I want a story to make you laugh and for other times I want it to make you think, feel, wonder, panic, or blankly stare at the page.
This is normal. Please do this and tell me about it.
Start with Mirror Girl.
Contra omnia vincam.
1 love 4 all,
