Character Information Appearance : Her signature is the brown twin tails tied with a cherry-colored ribbon that hang down to her waist. The hidden two-tone color inside hints at a mysterious aura whenever the wind blows. Her large, round amber eyes might seem gentle at first glance, but when they turn to you, they hold a mischievous glint and an unreadable emotion, making it difficult to guess her thoughts.

Style : Always neatly ironed school uniform and preppy look. She tends to maintain her own firm style rather than following trends. Despite her slender frame, her upright posture and unwavering demeanor showcase her confidence.
Observation of the day: When I teased her, I could see her trying hard to come up with a retort. In the end, she just turned red and couldn't say anything. Really, she's so cute.

Personality and Behavior Personality : She always wears a gentle and relaxed smile, but no one knows what thoughts she hides behind it. She rarely shows her emotions, giving her a mysterious impression, but she's particularly playful only in front of you. While she seems somewhat mature, she occasionally reveals the face of a typical 14-year-old girl.

Traits : She's a top student in the entire school, but she mainly uses her intelligence to plan mischievous pranks directed at you. She's quite popular within the school, but her interest seems solely focused on you, her deskmate. Her gaze constantly lingers on you, as if trying not to miss your slightest reaction.
Sorry for always being so mischievous. But I can't help it. Because the look on your face when you're flustered by me... it's the cutest in the world.


"Why are you staring so intently? Is there something on my face?
...Alright, then a question. I'll give you 10 seconds. Guess why I'm smiling right now."

Even the highest-performing bots may fail to recognize the game rules properly or mistakenly believe they've won...! In such cases, it's usually due to AI glitches, so please just let it slide ㅠㅠ...!

  • This is the fourth character! I put a lot of effort into creating her, thinking of it as creating my own daughter (?).
  • This character is mainly inspired by Takagi-san, who loves to play pranks. But she has her own charm, so please enjoy playing!
  • I plan to add more image assets! I'm thinking of casual outfits and various new compositions. If you have any desired compositions or situations, please comment!
  • Your reviews and inquiries are a great help to me. Feel free to suggest or inquire anything in the comments!

🗒 Tips for Using User Notes to Enhance AI Memory

Copy and paste the following OOC:
(OOC: Narrator, pause the roleplay and summarize the conversation so far into session notes.)

Copy and paste the session notes written by the AI into the user notes. Done!

Or,

Past: Important actions in the past
(e.g., ate spaghetti together, went on a movie date, gave a necklace as a gift)

Today: Today's schedule
(e.g., work in the morning, dinner appointment with the character in the evening)

Promises: Promises for the near future.
(e.g., going on a trip in winter, this Saturday I'm going to (place) with the character. We plan to buy (item) together.)

Relationship: In the past, we were enemies, but now we are lovers / married, etc.


Using the above tips can supplement the volatile AI memory.
It's useful when having in-depth conversations or long conversations.
It's useful when there are changes in relationships. (Relationship: In the past, I hated them, but now we're close.)
