Top left-hand corner - Eye & Compass: The eye shows how much vitality you have left. As you take damage, the eye will gradually close. When you have 1 or more full vials of thin blood, the eye colour will turn from blue to red. You'll know when you've run out of thin blood when the eye turns blue again.
Top right-hand corner - Messages & Combo count: Various messages will display here as you gain blood, as well as the number of consecutive combos (critical hit kills).
Left side: A separate screen appears when the special ability button is pressed while aiming. This side screen also appears when you gain thick blood (from critical hit kills and such). For personae who have the charge shot ability, a charge gauge will be displayed - 3 tubes. Press [] (PS2) or Y (GC) to increase the charge level. The higher the level, the more amount of thin blood will be consumed. The charge level is displayed above the gauge, with the amount of thin blood vials that will remain after consumption indicated beneath it. The image under the charge gauge just shows thick blood being absorbed, which leads to the large tube shown on the submenu.
The crosshair: The crosshair will contract when locked on a target or a critical spot.
