Let me remember first since it is quite a long time, when i was in high school XD. Yah i finish the EX Mode too using modifier SMG , i think this is the best weapon it has many slot you can add status effect, and because the area were not quite big, SMG better in moderate range. Shotgun also best for that range but gap between first shot and next shot quite annoying.

Part that i like in PE 2 special weapon Hyper velocity weapon and Gunblade, well yah Aya a bit chubby there XD but on FMV she doesn't look that way . My nose bleed on Aya bath scene kidding
