OSSS Mission 1: Alien Elimination

You've been issued a special mission from the OSSS. You can complete it if you have the OSSS任務1：指令書.

I see that you have the OSSS任務1：指令書. I will issue you Mission 1.

Aliens have been appearing throughout Maple World. Please defeat 20 Unidentified Powerful Aliens, 20 Unidentified Wise Aliens, and 20 Unidentified Lucky Aliens.

Remember, aliens can't be hurt if you're not wearing the Bing Machine.

You will get a medal when you complete the mission. Talk to 選任研究員ゼット to upgrade your suit using those medals.

Idle chat can wait until after you've saved Maple World...

Have you completed the mission?

Thank you for your work. Here is your medal. Head over to 選任研究員ゼット to purchase various cells that can be used to upgrade your suit.

And as for the OSSS任務1：完了確認書, submit it with the other ones once all four missions have been completed.

Looks like you haven't finished the mission just yet...
