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 殺(ころ)すのはダメーッ」
“K-killing it is not okay!”
琴葉(ことは):
「でも こんな化(ば)け物(もの)ブッ殺(ころ)すべき」
“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ブッ殺(ころ)すべき = should kill
  • べき attaches to the dictionary-form verb ブッ殺(ころ)す, 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こんな化(ば)け物(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 化(ば)け物(もの) makes Kotoha’s べき sound more justified from her point of view.
4ブッ殺(ころ)す is rougher than 殺(ころ)す
  • The prefix ブッ adds a forceful, violent feel, closer to “kill outright” than the plainer 殺(ころ)す.
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) means capturing a wild animal alive or catching a fleeing person.
