Blurb[]

Welcome, Sensei. As you can see, the D.U. Shiratori City restoration project is underway.

~ to Sensei, Visiting

This is D.U. Shiratori City.
Anywhere you look, it's the same situation. But that's even more of a reason to hurry with the restoration here.

~ to Sensei, Visiting

You called, Sensei? What can I do for you?

~ to Sensei, Tapping

Because so many students are pitching in, the restoration has been going smoothly.
I'm very glad that I asked Schale for help.

~ to Sensei, Tapping

It looks like you're feeling better.
...I'm relieved to see that.

~ to Sensei, Tapping

After all, destroyed buildings can be rebuilt...
But once you lose your health, there's not much to be done.
So please, don't push yourself past your limits.

~ to Sensei, Tapping

We’re nearing the end of the restoration project.
Thank you for all your hard work, Sensei.

~ to Sensei, Visiting, Event Ending

The Shiratori City restoration project has been completed.
Would you mind coming with me to take a look at the site?

~ to Sensei, Visiting, Event Ended

Event Guide[]

  • Stages are likely required to be cleared twice. If teachers don't have the upgraded event students; It's easier to clear the stage twice: to get the 3★, bonus student drops, and thus the maximum reward.
  • Once an area has been perfectly cleared, at 3★. The stage reward given is always the highest recorded drop, including the bonus from the students.
    • Using the "Skip or Rush" function will record the highest drop.
  • In this event, teachers can farm event currencies through the quest stages and skill material through the event schedule
    • Materials (Ooparts)
      There are 4 types of materials that teachers are able to obtain and each can be obtained from tier 1 to tier 3. There is no event bonus for these materials and their drop rates are very low.
      • Crystal Haniwa⁠ ~ Room 1 / Room 5
      • Nebra⁠ ~ Room 2 / Room 6
      • Voynich⁠ ~ Room 3 / Room 7
      • Ether⁠ ~ Room 4 / Room 8
    • Event Currency
      Generally, event currencies dropped on all quests with the higher difficulty giving out more and can be doubled should teachers bring along all students with event bonus.
      • Safety Helmet⁠ ~ Quest 9
      • Financial Statements⁠ ~ Quest 10
      • Mentai Potato Chips⁠ ~ Quest 11
      • Event Point⁠ ~ Quest 12

Heehee. Are you playing hooky too?

*sigh* City restoration is so annoying...
I wish every D.U. building sold snacks.
Then I'd be able to eat pollock roe any time I wanted...!

~ to Sensei, Tapping

I've never been this busy in my whole life...
But I guess I owe you one, and it's probably good for me to be active every once in a while...

~ to Sensei, Tapping

Oh, you need that?
Sure. Take as many as you want.

Okay, okay. You can have it. Come again.
