TsundereSQL Demo

Like Module 1? The full game has 14 modules and is coming soon. Wishlist TsundereSQL from the link at the top of this page.

All of Module 1, start to boss.

TsundereSQL is an anime visual novel built around a full SQL course. This demo is its first module. You write real queries against a small practice database for a crypto exchange, Tsumugi marks them, and each answer is checked on hidden test data as well as the sample you can see.

• All 18 questions of Module 1, ending in its boss.
  
• Hints that go from a nudge to the answer, and a short lesson for every question.
  
• Errors explained in plain English, next to the database's own message.
  
• A short animated example of the logical order SQL clauses are evaluated in (FROM, then WHERE, then SELECT).
  
• Tsumugi's texts on a phone. A new one arrives at questions 2, 5 and 10.
  
• One free outfit pull.
  
• 24 optional SQL drills, which you can open at any time.

The first five questions are guided: you fill in the missing part of a query before you get an empty editor. After that you sort and page with ORDER BY and LIMIT, label rows with CASE, and work with dates, text and missing values. The last question is the boss, The Compliance Blotter, which needs all of it in one query.

Your first correct answer unlocks a short scene with Tsumugi, and the boss has its own scene before and after.





After question 3, Tsumugi gives you one free pull: a gashapon crank, a manga cut-in and a holo card. In the demo it is always the same outfit, her Stage Idol costume. You can wear it for the rest of the demo or keep the uniform.



In the full game, solved problems earn gems, and gems buy outfit pulls. There is nothing to buy with real money.



The full game has 224 problems across 14 modules, from your first SELECT to joins, window functions, CTEs and messy, realistic practice data. Tsumugi, Aimi and Nora each have their own story, earned by solving problems. The demo home has a row of cards on what else is in it, including the Incident Room, where you work out why a report is wrong.


Good to know

• No account or internet connection is needed to play. Your progress is saved on your computer.
  
• The demo sends anonymous counts of how far players get, with no ID and never your queries. They are on by default, and one click turns them off.
