Warning of White Chalk - Where Aesthetics Reside in the Mansion of Deception (「白亜の予告状~虚飾の館と美学の在り処~」) or Alabaster Calling Card on Global, is the 24th event in Blue Archive. Set on a mansion hosting an art exhibition, featuring students of Game Development Department and Toki.

Blurb[]

Momoi was asked to "clean up" at a game center. The client mistakenly thinks Momoi is Neru from Cleaning&Clearing. Momoi and the entire Game Development Department accept the job without realizing it and change into maid uniforms and pretend to be C&C. Will they be able to complete the request? The curtain now rises on the slapstick mayhem surrounding the phantom thief and the artwork!

There's so many people here... I'm not used to crowds...
But this is sort of like a special event, isn't it?

~ to Sensei, Visiting

Sensei! Um...
Welcome, Master.

~ to Sensei, Visiting

T-The chest... Where is the chest...? Without it, I...
Oh! You found it!
Thank you, Sensei.

~ to Sensei, Tapping

Um...even though it was scary...
This whole thing might actually be good inspiration for the game I'm working on...

~ to Sensei, Tapping

Sensei, will...will I do okay?

~ to Sensei, Tapping

Ugh... I really want to go home and play games...
But I can't just sit here trembling... That's no good.
After all, if I don't try to do everything I can...

~ to Sensei, Tapping

Sensei, please let me know if you see Neru anywhere.
Promise me, okay?

~ to Sensei, Visiting

My loadout is equipped! I am ready to go! What about you, Sensei?

~ to Sensei, Visiting

Please hurry, Sensei! It is a very special quest!

~ to Sensei, Visiting

My maid level still isn't very high...
But I will continue to grind for it!

~ to Sensei, Tapping

Cooking, cleaning, laundry... A maid must know many skills.
Will you join this quest with me, Sensei?

~ to Sensei, Tapping

Um, you can hit me, but I am not going to drop any loot...
I am not a mob!

~ to Sensei, Tapping

Welcome, Sensei.
Preparations are complete for the stealth mission.

~ to Sensei, Visiting

Yes, Sensei. What is it?

~ to Sensei, Tapping

Ha... In these clothes, it feels really...
But the fabric is so thin I suppose that's inevitable...

~ to Sensei, Tapping

You mean the bunny suit?
The strengths are different than the maid outfit. It's good in the right situations.
You think I look good in it?
Hm... Well, thank you. I didn't expect that...

~ to Sensei, Tapping

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 a lot of items:
    • Materials (Ooparts)
      There are 4 types of materials that teachers are able to obtain and each can be obtained from tier 1 to tier 4. There is no event bonus for these materials.
      • Baghdad⁠ ~ Quest 1 (T1/2) / Quest 5 (T2/3) / Quest 9 (T2/3/4)
      • Antikythera⁠ ~ Quest 2 (T1/2) / Quest 6 (T2/3) / Quest 10 (T2/3/4)
      • Phaistos⁠ ~ Quest 3 (T1/2) / Quest 7 (T2/3) / Quest 11 (T2/3/4)
      • Disk Pendant⁠ ~ Quest 4 (T1/2) / Quest 8 (T2/3) / Quest 12 (T2/3/4)
    • Event Currency
      Generally, event currencies dropped on all quests with the higher difficulty giving out more and can be doubled should teachers bring along students with event bonuses.
      • Pretty Headband⁠ ~ Quest 10
      • Makeup Set⁠ ~ Quest 11
      • Mansion Invitation⁠ ~ Quest 12
