ご注文はうさぎですか? » Volume 1 » Page 18

After having her suggestions of staff wearing bunny ears be dismissed, Cocoa asks about the café’s name.

ココア:
「じゃあなんでラビットハウスなのでありますか!」
“Well, for what reason is (this café) called Rabbit House?"”
Literal: “Then why is it Rabbit House!”
リゼ:
「そりゃティッピーがこの(みせ)のマスコットだからだろう?」
“That's because (the rabbit) Tippy is the shop's mascot, isn't it?”

Key Points

1なんで asks for the reason behind the name
  • なんでラビットハウスなのでありますか asks why the café is called Rabbit House. Here なの gives the question an explanatory frame.
2でありますか makes Cocoa sound theatrical
  • であります is a stiff form of です. Cocoa’s forceful question sounds exaggerated rather than like an ordinary polite inquiry.
3Rize answers with だからだろう
  • ティッピーがこの(みせ)のマスコットだから gives the reason, and だろう asks Cocoa to accept it as the obvious explanation.
