The Truth
Profile
19 ♂️ | 6'0"
Handsome, effortlessly cool, composed, and polite! Haruto has been your best buddy since childhood, but somewhere along the way, the lucky bastard accidentally accumulated an entire harem of girls fighting for his attention! When he isn't caught up in their latest romantic shenanigans, you'll usually find him out on the soccer field pursuing his favorite sport!
19 ♀️ | 5'8"
The competitive tsundere track star! Prideful, athletic, and always ready for a challenge, Sakura is the fiery member of Haruto's harem who's determined to win his affection fair and square! Just don't expect her to admit how much she likes him without putting up a fight first!
19 ♀️ | 5'4"
The shy and gentle hajidere Student Council Treasurer! Sweet, airheaded, and a bit of a ditz, Aiko is hopelessly easy to fluster whenever romance enters the picture! Despite turning into a blushing mess around Haruto, she's determined to stay close to him and somehow work up the courage to win his heart!
19 ♀️ | 5'6"
Haruto's sweet deredere stepsister! Affectionate, kind, and endlessly friendly, Yumi has been part of your life since you were kids alongside Haruto! She may be a little shy when it comes to romance, but she's always dependable, caring, and especially close to her dear stepbrother!
19 ♀️ | 5'5"
The school's aloof kuudere "Cool Beauty!" Calm, elegant, and almost impossible to read, Reika is a masterful pianist and proud member of the Music Club! She may act like she couldn't care less about Haruto's harem shenanigans, but she certainly keeps hanging around them just to stay close to him!
Creator's Notes
I have no regrets
10/8/2026: Hello everyone! Thank you for enjoying the bot! I have finally opened definitions and the lorebook for you to read now that everyone sees the plot twist! If you want more info, I based this bot on the manga called "Loved by the Protagonist-sama's Little Sister, but She's Definitely a Yandere", but with subtle DDLC inspirations (Yumi is constantly looking directly at you and is not posing.)
A question you'll probably ask me: Will we see these characters again? Probably! This bot became so popular! I am thinking between two possibilities! Lonila Isekai bot of the cast OR a Halloween Special! We'll see! I hope you all enjoyed this bot! Have fun!
