ShiroKuro

ShiroKuro is the third Raid boss of Blue Archive. The fight consists of two stages, one versus Shiro and one versus Kuro.

Shiro will throw bombs at your students in unpredictable and often destructive manner, while Kuro will line up teacups against your students in a predictable, but equally destructive manner. Success in ShiroKuro may require players to utilise various tools of survivability through the means of self-repositioning (Izuna, Asuna), repositioning via pick-ups (Serina, Fuuka, Kotori), or utilisation of cover/summons (Shizuko, Shimiko, Utaha, Hifumi).

Additional Notes:

• The time limit for this fight is 4 minutes
• All of the bosses EX skills have a knockback effect. No damage or knockback will occur if students are not standing in the skills area of effect.
• The stagger gauge will accumulate under the following conditions:
  • The bosses are hit by Mystic type damage
    It should be noted that in extreme difficulty, the required amount of damage to fill the stagger gauge is higher than the boss's HP, meaning it is impossible to stun them with this condition.
  • When Shiro's ball is bounced back after failing to destroy cover generated by the likes of Shizuko or Shimiko
  • When Kuro hits herself with her own skill
• When the bosses are stunned, "Rolling roll!" and "Charge!!!" will be cancelled, but "Dokkaan!!" will not be cancelled.
• As the ATG increases, not only does the damage for "Rolling roll!" increase, but also the number of bombs generated and their explosion range.
  Shiro will attempt to aim at least one bomb on a student, with the rest being randomly (?) placed.
  A student can be hit by and bounced between multiple bombs.
• Shiro uses "Rolling roll!" at fixed times.
• Kuro uses "Charge!!!" about every 15 seconds
  Once launched, the skill will only damage the first student it hits before disappearing. If the skill spawns on top of a student already occupying that position, the student will take damage and be knocked back, but the skill will not disappear and still launch as normal.
  The attack patterns appear in a fixed order, and will be reset to the first pattern after recovering from stagger.

Recommended Units

Recommended Units
	Haruna is one of the best blue DPS in the game right now. Her EX cost can be reduced down to 3 at max which makes her even better and is easily one of the best characters you can bring to this raid. Queen of Urban terrain, will carry you if Shirokuro is held indoors.
	Shirokuro is the best place to use Izuna and the raid where she really shines. Izuna's 3-cost EX relocates her and buffs her which is extremely useful for a raid like this where you want to constantly relocate your students or move them out of harms way. She will also deal great damage with her kit and is easily one of the best characters for this raid since it was made for her.
	Requires high investment but she can be extremely useful in this raid due to being able to relocate herself with her EX skill as well as being buffed by it. Solid 9/10 used in many strategies such as no healers strategy or budget strategies but she is ultimately inferior at 5* than a base Izuna or Haruna with maxed skills.
	Needs a fair bit of investment but is a Mystic DPS character that starts at 2* so she is more accessible than Haruna or Izuna. Better at Perorozilla than Shirokuro due to the AOE nature of her attacks but is still a solid pick for this raid.
	Not your best pick for Shirokuro but is the goddess of the Perorozilla raid and the best mystic DPS for that raid due to her linear AOE attack. Can definitely fill a slot if you need one more team member but the premium DPS for this raid are Haruna and Izuna.
	She's yellow but will deal surprisingly high damage if you need to fill a slot and might even outdamage some of your other mystic units that have low investment. Definitely worth slotting in if yours is invested or strong.
	Staple support on most teams for everything. Buffs attack with EX, debuffs enemy attack and has a passive skill that increases team attack. Really wants 3* to unlock said passive skill so keep that in mind.
	Staple healer when you want to live. If you need a healer then Serina will be your healer of choice for most things. Her medkit box can move a student to where you want her to be which is extremely useful in most situations.
	Deals good mystic damage and can reduce a targets defense with her attacks. Her defense down stacks with other characters such as Maki, Akane or her red version so it is possible to have double defense down on an enemy. Queen of Indoors terrain, will carry your Shirokuro if it's held indoors.
