## What it is
osakaOS is a 32-bit hobby operating system written in C++ with intentionally unconventional design, themed around the anime character Osaka. It boots from an ISO in emulators like QEMU and includes a multitasking kernel, custom filesystem, GUI desktop, paint program, networking utilities, and the AyumuScript scripting language.

## Use cases
- boot a silly toy operating system in QEMU
- learn how a hobby OS kernel works by reading C++ source
- write scripts in a custom scripting language on bare metal
- run a retro demo-style desktop environment in an emulator
- explore a custom filesystem implementation
- use a paint program inside a from-scratch OS

## When to choose
- you want a fun, unconventional hobby OS to explore in a VM
- you're learning OS development and want a quirky real-world example
- you enjoy demo-scene or videogame-like bare-metal software

## When to avoid
- you need a reliable daily-driver operating system
- you need data safety, error handling, or modern hardware drivers
- you want a production-grade kernel or networking stack
