Doomed Otaku: Achievements and Endings Guide
Spoiler warning: this guide reveals a lot of story text, choices and events. It works best after you have seen several endings and know the world.
Overview
- Doomed Otaku has 42 achievements: 3 story achievements, 4 minigame achievements, 15 special achievements and 20 ending achievements.
- 12 of them are hidden. They are marked as hidden below and are not listed separately.
- Reading the story carefully, all achievements take about 25–30 hours. Skimming or skipping most of the story cuts this to about 10–15 hours. Both are rough estimates.
- Special achievements are split into an Idol☆Star part and a real-world part, so you can find them easily and do each group in one go.
- The game is newly released, so later updates may change some of these details.

Spend 3 MAX SP in the White Space on the [Trash Lover] ability, then search trash cans. There is a chance to find the Wondrous Mouse. Summon her as a pet and walk up to a trash can, and she empties it in one go.
Money Sources
Each method below pays differently, so pick the one that suits the achievement you are working on. The figures ignore the 1 SP you spend going out early in the day.
Landlord’s Daily Tasks
- Delivering notices as apartment manager: 1,500 / 8 SP
- Apartment cleaning: Gold Bell, 333.33 / 2 SP
- Important delivery: 50 for bus fare, 1,000 / 4 SP
- Sorting the bills of the last apartment: 5,000 / 2 SP
- Driving out the mysterious cult: 1,000 / 4 SP, plus a red bean bun worth 3
- Pros: the tasks are simple and fun.
- Cons: some of them pay little.
Borrowing From Jin Taiyang
20,000 / 2 SP
- Pros: you can borrow on January 3. Then you only need 5,000 or more on January 4 for the normal ending.
- Cons: the loan leaves you with no money to spend freely.
Working at Banban Delivery
500 / 5 SP
- Cons: the pay is very low, the work is tiring, and later you have to compete with robots for jobs.
Searching Trash and Selling Junk
This assumes you have the [Trash Lover] ability.
- Example: selling 262 items earned about 25,000.
- 1 SP turns up 2–3 pieces of junk, so expect about 250 / 1 SP.
- If you find the Wondrous Mouse, let her out. She keeps searching trash cans for you, which makes this almost pure profit.
- Pros: it helps with several related achievements, and once you have the mouse you barely need to do anything.
- Cons: the return is low when you pay SP for it.
Reselling Shotaro Badges From Blind Boxes
Buy blind boxes of merch at Coffee Taco and sell the Shotaro badges.
- Example: 100 boxes gave 22 Shotaro badges. Cost: 100 × 250 = 25,000.
- The otaku who only collects Shotaro buys each badge for 1,500. Income: 1,500 × 22 = 33,000.
- Net profit: 33,000 − 25,000 = 8,000.
- Pros: buying boxes takes no time and no SP, so you can grind it slowly.
- Cons: opening boxes is dull and needs a lot of starting money. Only the Shotaro badge earns back its cost.
Staging Accidents With Luxury and Gold Cars
- Luxury car: about 2,500 / 5 SP
- Gold car: 500,000 / 5 SP
- Pros: one gold car sets you up for life.
- Cons: staging accidents takes some skill, and gold cars are rare, so you have to wait.
Digging Up Treasure for Ou Yi’an
- Example: handing in 99 treasures at once paid between 45,000 and 49,000.
- That works out to about 47,000 / 198 SP.
Finance Expert and Past-Life Savings
- [Finance Expert]: earns 10% of the previous day’s savings every day.
- [Past-Life Savings]: depends entirely on how much money you had in your previous life.
Summary
By SP efficiency: gold car > borrowing from Jin Taiyang (emergency loan) > apartment bill sorting > luxury car.
These four reach 500 per 1 SP. The other methods depend on your situation.
