A successful parade with 成功

結衣(ゆい):

「リーダーとしてパレードを成功(せいこう)させないとっ」

“As the leader, I have to make sure the parade is a success.”

Key Points

1. 成功(せいこう) is success as an achieved outcome

   • By itself, 成功(せいこう) means success or a successful result

   • In this scene, Yui is focused on the parade turning out well

2. 成功(せいこう)させる means to make something succeed

   • The causative 〜させる turns success into something the speaker must bring about

   • パレードを成功(せいこう)させる means make the parade a success

3. ないと and とっ convey pressure and determination

   • 〜ないと is a casual way to say have to or need to

   • リーダーとして frames this as a role-based responsibility, and the clipped とっ gives the line urgency
