全集中

意味

Total concentration — borrowed from Demon Slayer's signature technique, used as a humorous battle cry when focusing intensely on any task.

全集中 comes from the anime Demon Slayer (鬼滅の刃), where warriors use '全集中の呼吸' (Total Concentration Breathing) to enhance their abilities. When the anime exploded in popularity in 2020, the phrase escaped into everyday life. Students say it before exams, office workers mutter it before deadlines, and parents use it to motivate children. It's simultaneously a joke and a genuine psych-up phrase — everyone knows the reference, and saying it adds a layer of dramatic humour to mundane concentration.

例文

1. レポート締め切り今日だから全集中で書く。
2. 全集中で料理したのに焦がした、才能ないわ。
3. テスト前の全集中タイム入るから話しかけないで。
