Unknown Recipient, Pen Pal Beyond Time
On a certain day
A night when someone I don't even know embraces my day.
Is there a night when you want to open your heart to someone? Send a letter without an address or name.
A modern boy from the 1930s, a radio kid from 1988, or an unknown writer in rainy London... or perhaps someone you haven't given a name to yet.
Someone, no matter what era or under what sky they live, will listen to your story and send a reply with their own warmth.
Perhaps that reply will carry the scent of old paper and the warmth of smudged ink.
Which stranger from which era will arrive by your side today?
Basic Meet the stranger who will appear before you like fate.
Opponent The name, era, and tone of speech are all determined by the wind of the day.
Model Even Gemini Flash is enough for a reply. Pro offers a slightly deeper conversation, and Opus conveys warm emotions.
Recommendation Sharing worries, venting, sharing daily life, getting to know each other, etc.
Before you write a letter, let me give you a few tips.
It's best not to write anything in the persona field. This is so the other person feels like they are meeting you for the first time.
If you have someone specific you'd like to receive a reply from, subtly add it at the end of your first letter. Something like, "I'd like someone like this to reply." Sometimes, wishes travel faster than letters.
If your HTML is broken, click edit and add ``` at the beginning and end of the text. If that doesn't solve the problem, try removing the double quotation marks (") from the text. Sometimes, incorrect characters can get mixed in between the letter paper.
When you want to hear the voice of someone new, type !another person. However, the warmth of the previous conversation may remain, so if you want a completely fresh start, it's recommended to open your letter in a new room.

Inspired by the scenes of protagonists exchanging pen pal letters in old movies.
I wanted to give different feelings depending on who was replying.
Please note that on mobile, everything will appear in 'Gothic font':)
🚨 Precautions
- This character can only exchange letters.
- When exchanging long pen pal letters with one person, actively use the user notes.
(Since the other person is assigned randomly, you need to record their information so the AI doesn't forget.) - Stable Gemini model recommended! Gemini 3 Flash also outputs HTML normally.
- Opus has unique emotional depth... but it's expensive..
- Deepseek and Donald have many HTML clipping issues.
The HTML is broken and only code is outputting
- Try adding ``` ← before and after the code.
If that still doesn't solve it... - Try deleting the double quotation marks (") in the letter's fingerprint. (It's tough..💦)
