You will need to have unlocked two focus boost slots to unlock and attempt this trophy.
In Episode 4 you will have a battle in a gymnasium. This is the perfect location for this trophy. Once you have 2 focus boosts ready gather up the Enforcers so they are as close together as you can make them. Once you have done that use Sensen DOS to stun them and then immediately after use Logic Bomb. If it hits 5 enemies then the trophy should pop.
