Yui, Sacchan, and Kotoha are friends who’ve formed a group called Colors to protect their neighborhood. Yui is the group’s leader.

Yui hurries to the Colors clubhouse with news of a cat she saw. She draws it on paper, but Sacchan sees it as the sketch of a monster. Kotoha looks over the drawing and asks if they’re going to kill it.

結衣(ゆい):
「こ (ころ)すのはダメーッ」
“K-killing it is not okay!”
琴葉(ことは):
「でも こんな()(もの)ブッ(ころ)べき
“But a monster like this should be killed.”
さっちゃん:
「そうだ じゃあ捕獲(ほかく)ならいいかリーダー」
“Right. Then is capturing it okay, Leader?”
結衣(ゆい):
「うんそれ!それにしよう!」
“Yeah, that! Let's do that!”

Key Points

1ブッ(ころ)すべき = should kill
  • べき attaches to the dictionary-form verb ブッ(ころ), so Kotoha is stating what she thinks the proper action is.
  • The subject is omitted. In English, “a monster like this should be killed” keeps the focus on the monster rather than naming who should do it.
2べき gives a judgment, not a hard rule
  • Kotoha is not quoting a law or requirement. She is giving her blunt opinion that killing the supposed monster is the right choice.
  • That fits べき’s nuance of ought to or should, stronger than casual advice but short of must.
3こんな()(もの) frames the target harshly
  • こんな means “this kind of” or “like this”, and it points at Yui’s drawing.
  • Calling it a ()(もの) makes Kotoha’s べき sound more justified from her point of view.
4ブッ(ころ)す is rougher than (ころ)
  • The prefix ブッ adds a forceful, violent feel, closer to “kill outright” than the plainer (ころ).
5捕獲(ほかく)なら shifts the proposal
  • Sacchan changes the action from killing to capture with じゃあ捕獲(ほかく)なら, “then if it’s capture…”

Vocabulary

(Capture)

捕獲(ほかく) refers to the act of catching wild animals, fish, insects, and the like while they are still alive, or of apprehending a fleeing person or object.
