His fight consists of three parts. You'll be fighting him normally but once his HP reaches a certain threshold, he will run away to another place and force your girls to chase him and relocate, starting the second part. The fight will proceed normally again until his HP meets a certain threshold again where you will be interrupted with a cutscene and your characters will be forcibly relocated to where you were before to continue the fight.
Every time Binah takes damage from a penetration student, his stun gauge will rise. When the stun gauge is at max, Binah will get stunned for a few seconds and use his Purifying Storm move if you are on the 3rd phase. The first run of Binah was in an outdoors setting and the second run of Binah was in a Urban setting. On the second run and beyond, Binah was changed so his 'Conflagration of the Ultimate way' skill will have a cooldown and can't be used multiple times in a row.
Excellent for this raid and the top DPS by far. Her 3-cost damage EX is amazing in this raid but make sure to time it when both def downs are up if you're using Maki and Akane for best burst potential.
Has good damage and a defense down skill. Her defense down skill is on a set timer so make sure to time your bursts when her defense down and Akane's defense down are up if you are using both. Maki's damage output scales really well at high investment when Unique weapons and Ako buffs are available, this makes it viable to run single-dps team where all other members are focused on supporting Maki.
Her sole reason to exist in this raid is to apply her defense down skill. Make sure to apply her defense down and to keep it up at all times without allowing for it to fall off. Her defense down being 2-cost also makes it good for skill cycling.
Only recommended if 3-star. Pina gains a skill that increases her damage when not moving and your characters will stay in one place for the great majority of the fight so she's a great damage dealer for this fight.
Other recommended students
Her damage will take a hit because it's not recommended to bring Momoi to this raid considering her damage is AOE and this raid is Single target damage but Momoi will be a good alternative if you lack Iori as a single target damage dealer considering her 3-cost skill deals good damage for very low cost.
Free to 3-star and a great penetration damage dealer. Downside is that her EX is AOE and this raid is all about single target damage. You could opt to just not use her skill if you have other units that can deal good single target damage but she's a good filler if you lack the recommended units.
Neru's 2-cost EX has strong damage against a single unit for very cheap so she is also a good unit for this raid.
A free to obtain character, she performs well in this raid as a unit with solid damage and a strong 5-cost skill that deals damage to everything in a line. Great filler if you lack the recommended units and possibly recommended over Nonomi if you're making a welfare team.
It's not recommended to bring a tank to this raid at all but she can be filler for one of your teams. Make sure to use her EX to position her away from the rest of the team and close to Binah so she can tank most of the hits for the team.
See above. You would have to use Serina or something similar to move Tsubaki because she doesn't have an EX that makes her move like Hoshino.
Starter penetration unit. Not your best choice since you would be better off with any of the above ones.
Strong penetration dealer. Her 4-cost skill deals damage to a single target and the damage is increased if the target is big/large so she's excellent for this raid.
The best healer in the game for anything you want to do. Her 2-cost skill will summon a first-aid kit that will make the closest unit run to it to heal themselves. Only worth considering if you're taking too much damage and require a healer, otherwise go full damage.
Her 3-cost skill will buff the attack units in the circle and is cheap so you can use it to cycle to your other units skills while buffing them. Way better at 3-star but her subskill overlaps with Karin.
