After reaching elevator shaft turn right where after a while you find Lost Soul. Now return to the beginning place and go left. Use Angel Boost to pass a destroyed fragment of staircase.
Be ready for a short battle, starting from eliminating flying monsters and then finishing off a new Hell Knight. Resume marching toward higher floors, using Angel Boost and Pull on your way. Stop after using Pull second time. Turn around and place yourself as the screen above shows. Start using Angel Boost to get onto next platforms. Your goal is to get to another Lost Soul.
Return to where you've used Angel Lift lastly and resume marching. Jump into elevator shaft. You have to use Eryx gauntlets where the screen above shows - Stomp attack as with the crystals. Wait until you ride onto a lower level.
Move forward. After reaching a new room start from freeing the next Lost Soul. Repeat an action with Eryx, hitting the red mark on the floor.
Be ready, because a harder battle awaits. You have to defeat two Rage beasts. Use your attacks wisely and be especially careful if any of them get into fury mode. It's worth to focus on single target than attacking both of them equally.
BONUS MISSION: Stay where you've been fighting with Rage beasts. You find here Secret Door (1st screen) and if you have a Copper Key you can open them and begin a bonus mission Angelic Warfare (2nd screen). It isn't too difficult. You have to use only angelic weapons. As you already used to (with Frozen Knights for example), it shouldn't be problematic.
Use Angel Lift on the latch but don't hurry with leaving the warehouse. Turn around and use Angel Boost to get onto a shelf (screen above) where you find a Copper Key.
Return to the previous shelf and move on. After reaching a small room use a Divinity Statue and free the Lost Soul. At the very end use Angel Lift to get out of the building.
