Main Quest
Humanity's greatest unsolved problem
VISION
Defend the one hour of pool at dusk.
Humanity (me) is running out of time.
- ☀️Too hot (I don't want a tan)
- 🌙Too dark (feels like ghosts come out)
- 👙Too much hassle (no stamina to get out of bed and change)
The only window where I can safely play in the pool is 18:00–19:00 — exactly one hour. That this precious freedom is being taken from me is humanity's greatest unsolved problem.
So I stopped working.
- Annoying work ➡ throw all of it at the AI.
- Hard engineering ➡ summon a serious grown-up (the CTO).
My money, my clever AI and my staff all exist for one reason: so that nobody interrupts that one perfect hour at dusk.
Story
Story
Open a card and you get the honest version, lifted from my diary and my analysis documents.
EP.01Met generative AIStarted using ChatGPT as a partner that helps me think and build things.
the honest versionI begged the AI for help because I wanted my report over with. I threw every annoying thing at it, and for some reason the grown-ups started calling that “a new way of learning.”
noteFrom slacking student to conference speaker: 100 apps with ChatGPT (note, Japanese)
EP.02Won an award for a conference talkPresented my research and won the Young Researcher Award of the Network Software workshop. The researcher class unlocked.
the honest versionJust saying “I won an award” changed how adults treated me. It felt like picking up a handy pass that skips the tedious explaining.
noteNo inspiring story needed. My first win, taken with AI (note, Japanese)
EP.03Finished the 100-Day ChallengeDay one was Othello. From there, one game or app built and published every day for 100 days.
the honest versionI wanted attention. I kept going out of vanity — quitting would have been uncool — and before I noticed, the AI, the diary and the code had turned into a pile of material.
noteIndex: every one of the 100 works from #100DayChallenge (note, Japanese)
EP.04Joined an IT companyGraduated and joined as a new grad, equipping the mask of a salaried employee. Turned onboarding and company life into an observation subject.
the honest versionTraining was boring and I stuck out at the office. Playing a normal working adult hurt, so I turned it into a place to collect material while being paid a living.
noteCorporate tutorial: what eight months inside a big company taught me (note, Japanese)
EP.05Started writing “#100 Day Challenge”Began turning 100 days of work and diaries into a book.
the honest versionI wanted freedom, I wanted to be fussed over, I wanted out of a normal timetable. AI and an editor turned that desire into something shaped like a book proposal.
noteI was just keeping a diary, and somehow became an author (note, Japanese)
EP.06Judges' Special Award at an international conferenceReceived the Judges' Special Award at IEEE CogInfoCom, and a path to working worldwide came into view.
the honest versionIt gave me more reasons to go abroad and more material to inflate my profile. The practical upside came into focus before anything else.
EP.07Founded Hundreds LLCSet up my own company so work could be taken on by the company.
the honest versionHandling everything personally got annoying. Also, “we do it as a company” sounds more like a young founder, and looks properly put together. Putting myself in a box instantly changed how adults behaved.
noteThrough the tedious paperwork: how I set up my company (note, Japanese)
EP.08“#100 Day Challenge” publishedPublished by Nikkei BP. It became a bestseller, and talk and interview requests increased.
the honest versionJust saying “I'm an author” makes adults listen the first time we meet. It works like a very thick business card that lets me skip most of the explanation.
notePrologue: can skipping homework with AI make you an engineer? (note, Japanese)
EP.093rd place at a U.S. app-development contest3rd place in a U.S. hackathon with 55,000 entrants, and a prize of about $5,000. Proof, as a result, that I can build my own apps.
the honest versionI didn't want to be underestimated. If a profile can be upgraded in one shot, using AI, money and every grown-up around me was simply faster.
note3rd place at the U.S. app festival “Shipathon 2025” (note, Japanese)
EP.10Founded a U.S. entitySet up Hundreds US, LLC in the United States to make overseas work easier to take on.
the honest version“It's a U.S. company” sounded strong. Titles are clothes, so I changed into something that looks stronger.
EP.11Moved to ThailandLeft Japan and started living in a hotel with a pool in Thailand.
the honest versionI want the spa and the pool. I don't want to do housework. I want out of the tiresome air in Japan. I asked the AI, and my living conditions came out as “hotel with a pool, airport, spa.”
noteThe full record of leaving Japan, decided with AI in one week (note, Japanese)
PICK UP (note)
- Living on a 0.9 GPA without working — everything on how I dump it all on AI and walk away with the results (note, Japanese)
- “Who would ever buy this?” — how the diary I doubted became my strongest weapon in a year (note, Japanese)
- “I'd happily be a NEET forever” — the one-day job hunt where I gave up on working five days a week (note, Japanese)
- Turn your laziness into your strongest weapon: every prompt from my AI war room, the “Digital General Staff” (note, Japanese)
- What I'm plotting now (note, Japanese)
