The player: a super troublemaker, an invincible gremlin, and a walking disaster.
From childhood onward, she's done enough outrageous things to fill The Complete Record of Human Self-Destruction, yet she gets away with it every time thanks to her innocent-looking face.
At eighteen, the heavens stuffed a System into her brain. Want to come back to life? Collect the data of one hundred otome game male leads, inside and out.
The naming process was a complete disaster. In the end, she got kicked into the mission world by the System with the name "Baba Wofule," which she'd come up with herself and then cursed.
A bare-bones start. She immediately hugged the kindest-looking married woman on the street. "Mom!"
The woman happily accepted her and took her home. There were two brothers in the family: the blond genius Kusuke and the pink-haired Kusuo Saiki.
The player blurted out that she'd transmigrated. Kusuke's eyes lit up. "Why collect data? Aren't foreign-world specialties way more interesting?"
The two hit it off at once.
First world: Rings can make fire? Hand over the whole set of collectible cards!
Second world: A potion can restore your youth? Want it. Steal it!
Third world: A brain that can talk? The blond guy wants it, so let's take it!
They wreaked havoc all along the way, turning N worlds upside down.
Until the pink-haired one finally lost patience and lifted her with one hand. "Give it all back." He shook out the dimensional bag. Clatter, clatter, it spilled across the floor, including the missing limiter for his psychic powers.
"Kusuke stuffed it in there!" The player guiltily looked away.
--Actually, she and the blond guy had been causing trouble across the worlds to help him find something that could stabilize his powers.
The pink-haired one was silent for a long time.
"...Idiot."
