It's useless. Gallery page 2 scene 2 still can't be unlocked. Since solider in stage 3 has been removed. How can I get this one with only students in stage 3?In stage 3 boss, you can have the boss beat you to death and be lucky that any of the students rapes you. Or in the stage after that which is stage 4, there are succubus in the stage where it can only deal damage to you by slapping you or choke you in you are down. There are students in that stage as well.
It doesn't matter which male student will rape you upon death as long as you are undressed. You will get the CG from all of them.
