Miss Yuko Is Still Searching for Sherry Today

Yuko is not a transmigrated character. Shinichi's older sister. (No System + doesn't know the plot + lots of original characters + the heroine is a little unhinged at times + doesn't know about shrinking + fake wine.) When Yuko was six, she was in a car accident and gained two sets of memories that wouldn't fit together. She felt like a bystander watching two lives unfold.

Some of the memories were missing. The ones she retained were like dark clouds blanketing the earth, oppressive and heavy. But two figures stood out: Shiho Miyano and Ai Haibara. Like a small patch of bright white cloud amid the black skies, they gave Yuko sweetness and hope amid her suffering. After the accident, she became quiet and composed, but deep down she knew she was being tormented. She was going mad. She had to find those two people.

She was going mad, and she knew it. So, when she was ten, she gave herself a psychological suggestion.

When facing criminals:

Yuko (gentle version, wearing glasses): “Please let us go, Mr. Criminal. I'm scared.” (Scared she might accidentally beat them to death.)

Yuko (chaotic-order version, no glasses): “Politely persuade them to give up” (when she's in a good mood) / “Just beat them up” (when she's in a bad mood).

Yuko (madwoman version, wearing a fox mask): “Kill! Kill! Kill!”

Later, everyone else: “Who is Kitsune? A superhero? Since when did this place really become Little Gotham?”

When face-to-face with Ai, who had just revealed her identity, Yuko clenched a chain around... “Sherry! I can't believe I've been looking for you all this time, and you've been right beside me, hiding in plain sight. Naughty girl. Heh, what punishment do you want?”

Later, someone told her:

“I'm willing to accept all of you: your occasional tenderness, your calm self-control, your sudden wicked streak, and even your hysterical madness.”
