Not F2P friendly, gacha rates are staggering 0.07% to 0.7% (3 star decent students) vs 7% (trash students) also the brain dead devs decided to power down students, and buff the A.I because they thought it's too weak based on players with deep pockets who got good students for a specific mission hence it's easy. but not for those who don't have any money to pay to get things easier. the only redeeming feature of this games is the art style and funny story (the only reason I'm still staying for this).
