We're pleased to announce the release of Yurusen, a ledger-of-judgment app. In this post, we share the thinking behind it and its main features.
A place where you don't have to endure "unforgivable"
The world is full of phrases like "it's better to forgive" and "let it flow away." Sometimes those bring relief. But quite a few people, trying to force forgiveness while the wound is still raw, only end up hurting more.
We built Yurusen as a place to set that "unforgivable" feeling down, without having to endure it. File the person you couldn't forgive quietly into a ledger that is not public to other users, and draw a soft line under it. If you can't let go, you don't have to. Just get it out of yourself for now, so you don't collapse under the weight — that's what this private ledger is for.
Main features
- File into the ledger: record the person you can't forgive, with an alias and the offense. Real names can stay hidden.
- Seven levels of judgment: from Admonition to Ten Kings Descend, pass a judgment to match how you feel that day (all are in-app effects).
- Points: granted for free in a set amount each day. Use them for judgments; top up only on days you run short.
- Wraith Codex of 100: collect the "types" of unforgivable people as wraiths fallen into hell.
- Multilingual: currently available in Japanese, English, Chinese (Simplified and Traditional), Korean, Spanish, and Portuguese.
If you're new, take a look at How to Use Yurusen as well.
Using it with peace of mind
Yurusen is an app for private emotional care and entertainment. It is not meant to threaten, expose, or harass real people. Original entries are not public to other users. Cards and verses you choose to share can become public. The Privacy Policy explains when the operator may review entries. We recommend keeping real names hidden.
Writing is not an all-purpose solution. But getting a feeling with nowhere to go out of yourself, for a moment, without publishing the original entry to other users — that small step should make it a little easier to breathe.
We'll keep publishing here — reading on emotional care, introductions to the world of the Wraith Codex, and more. Thank you for being with us.
FAQ
Frequently asked questions
Q.Is Yurusen free to use?
Yes. The core features are free. The 'points' used for judgments are granted for free in a set amount each day, and you only top up on days you run short. The free allowance alone is plenty for regular use.
Q.What devices can I use it on?
You can use it in a web browser or the iOS app. Records are tied to your account, so you can open the same ledger even when you switch devices.
Q.Is there any risk of what I write leaking?
Original ledger entries are not public to other users. For entries created on or after August 12, 2026, the operator may review them for service improvement or investigation, and cards or verses you choose to share can become public. We recommend using an alias instead of a real name.
