Spoiler for PC3:

No, I had decided to go into the normal route first so I let the battle against Ikusa going on until it ended normally. I plan to go hard mode in my next playthrough.
Strangely enough, I had more SP troubles than tension problems during the last battle. To be precise, it was mostly Eiji who ended SP-starved when he arrived in front of the boss Guess that's the drawback from equipping him mostly with full hp recovery items than with the hp+sp recovery. And the boss' switching immunities wasn't helpful either *lol*. At least it gave enough time to charge tension when necessary
@Liliam: I let her soften the enemy up or get the killing blow so AoE wasn't really necessary as I usually sent Shirely and Mari together with her in one direction of the crystals. I gave her a Bind with an 400 AoE heal which made her slightly supportive, and helped me in the long run to smoothen things out. With so many binds, I tend to struggle somewhat to find an efficent setup (outside of the alicesoft wiki) and tend to keep the binds I'm about to level-up equipped during boss battles
