Subaru:  “You mean that game where someone is it and chases people, I suppose.”

Subaru:  “Yup, that’s the one. Except the rules are a little different. You’ll stay in the mansion proper, and you will be it.” When an invisible question mark formed above Beatrice’s head, Subaru clarified, “Right now, Emilia is running around the mansion. She’s the one you need to catch. But if all you had to do was chase Emilia and catch her, that would be too boring. Though I’d be super stoked if I were it.”

Puck:  “Subaru, Subaru, you’re going on a tangent,” Puck nudged him.

Subaru:  “Sorry. Anyway, while you chase after Emilia, you have to avoid getting caught yourself. If you catch Emilia, you win. But if you’re caught before Emilia, you lose—and there you have it. Double tag.”

Beatrice:  When Beatrice heard the game description, she frowned and twiddled her ringlets. “And I have to stay in the mansion proper? What about the garden or just outside the gate?”
gpt
Subaru:  “The garden is okay, but outside the gate is out of bounds. Also, no using your Passage or any other magic. Shifting planes makes you way too OP for tag, and magic can get people hurt.”

Beatrice:  “Hmph—that will put me at a disadvantage, I suppose. How am I supposed to catch Emilia without magic?”
gpt
Subaru:  “Use your brain, of course. Hide behind things, cut her off, et cetera. The same rules apply to Emilia—in the end, shrewdness will separate the winner from the loser!”

Beatrice:  “If you expect that explanation to entice me, there’s something wrong with you.” Beatrice frowned warily, but she was seriously considering the competition.

Beatrice:  “Very well. Game on, I suppose. However—the younger twin cannot be the one to chase me.”

Subaru:  “You noticed.”
gpt
Beatrice:  “Of course I did. Not even the great Betty is foolish enough to think she can beat an Oni in a contest of physical strength. I must take every precaution in that regard.”

Subaru:  In seeing through Subaru’s shallow wisdom, Beatrice smugly believed she had foiled his plan. If Subaru refused her caveat, there was no way that Beatrice would agree to the contest. Beatrice was in the right, after all. So Subaru reluctantly surrendered Rem’s participation. “After you leave, I’m going to count to a hundred before I chase after you,” Subaru explained. “Puck is going to stay behind in the Archive of Forbidden Books, so if you use your Passage to cheat, you’ll be caught immediately.”
