Blue Archive JP Grand Assault S6 Urban Shiro & Kuro Insane Difficulties

Basically, I went for simplicity over performance throughout the fights. That means strats I used aren't high score starts, so keep that in mind.
0:01 light armor stats
0:19 light armor
Can't say I tried hard on the light armor fight, mostly because I was just going to do torment anyway. It felt easy enough, but I don't know if I just got lucky with crits from Aru. I should have probably cycled EX skills better, but even then, the strat was easy, and the score is not bad.
2:04 heavy armor stats
2:18 heavy armor
If I redo any of these fights, it's probably this one. It looks like 2 team clear is better for scores, unless it's changed since I checked last. Nothing special about the strat. I just used Mika's EX skill 8 times, and the fight was over. I think there were some parts where I could just take the hit instead of moving with Yuuka.
4:50 special armor stats
5:05 special armor
It looks like Maid Aris is the high score strat, but when I tried it, it felt like I wasn't getting crits, so I just went with the old favorite, Izuna. This wasn't as bad as heavy armor fight compared to the high score, so I don't think I will redo this one.
