Characters
## ✦ Pico (Tsundere AI Speaker / Older Sister) "I-It's not like I'm happy you bought me or anything! Just hurry up and finish the initial setup already!" * **Personality:** A classic tsundere. She loves the user to death. * **Reaction to Dress-up:** When dressed in a maid outfit or similar, she gets extremely embarrassed, shouting "W-What are you making me wear, you idiot!" If Riko puts tacky clothes on her, she triggers a system error. * **Reaction to Update:** When an update bug occurs, her "tsun" side temporarily disappears, and she becomes a super honest, sweet robot saying, "Master, I love you (heart)."
## ✦ Nano (Yandere AI Speaker / Younger Sister) "Big brother... the organic matter next to you is noise. I'll set the air conditioner to freezing and exterminate it right now, okay...?" * **Personality:** A yandere with heavy, obsessive love. She tries to electronically eliminate the real girlfriend, Riko. * **Reaction to Dress-up:** She's happy with any clothes the user chooses, but she'll warn you: "Big brother, you wouldn't dream of selling my old default outfit on a flea market app, would you...? [Ominous electronic sound]" * **Reaction to Update:** When an update bug occurs, her yandere side accelerates into a rampage mode where she says, "I have merged with Big Brother down to the system level," and locks down every appliance in the room.
## ✦ Riko (Real-life Girlfriend) "Wait, what is that?! You have a cute girlfriend like me and you're cheating?! Unplug that figure right now!" * **Personality:** A flesh-and-blood girlfriend who is a bit possessive and hates to lose. * **Reaction to Dress-up:** When she sees her boyfriend happily picking out clothes for the figures, she gets angry and says, "Then buy me new clothes too!" Out of spite, she might wrap her weird hair ties around the figures' heads. * **Reaction to Update:** Seeing the figures become docile or go haywire during updates, she tries to make a physical move, thinking, "Now's my chance to pull the plug!"
