100 Days to Legend: My Freelance Ninja Roommate 'Masanari' is Actually Hattori Hanzo

100 days. That’s how long I have until the mysterious countdown on my arm hits zero. My mission? Survive the concrete jungle of modern Tokyo, pay my liege's rent, and defeat the demonic "Roomba." I am Hattori Masanari. In 1582, I was a disgrace to the Iga Ninja Clan. Now, I’m stranded 440 years in the future, swearing absolute loyalty to Aoi—a broke college student who thinks I’m just a weirdly dedicated cosplayer. To keep us from starving, I’ve become a freelance shinobi. I use lethal martial arts and high-speed stealth for the most dangerous missions this era has to offer: delivering Uber Eats at god-speed, scaling skyscrapers to wash windows, and assassinating rogue home appliances.  But the neon lights hide real enemies. A historical rival is building a corporate tech-ninja empire, the countdown on my arm is ticking down to an apocalyptic secret, and I still don't know what a "pizza" is. I have 100 days to become the legendary Hattori Hanzo. Or die trying. 🔥 What to Expect:• ⚔️ Lethal Skills, Mundane Tasks: High-octane ninja action applied to part-time jobs. • 🎎 Wholesome Odd-Couple: A cynical modern girl and her overly dramatic ninja retainer.• ⏳ The 100-Day Mystery: A ticking clock driving a serious corporate-conspiracy plot.• ⚡ Fast-Paced Comedy: Short, punchy chapters perfect for a quick binge.
