This game features eight playable characters, with four starting preset teams of two and unlockable individual character modes. When playing with the character pairs, one character fires when unfocused, while the other switches in and fires when focused, with a reduction in movement speed. The two shot types can be drastically different. The individual characters, with the exception of Remilia and Youmu, do not change shot types while focusing/unfocusing. Imperishable Night features Last Spells. For the enemy, a Last Spell is a bonus Spell Card which the player can challenge without the option to use bombs and without the risk of losing lives. On the player side, Last Spells are secondary "bomb" Spell Cards, which last longer and do much more damage than normal bombs at the expense of two bomb stocks. Player Last Spells can only be used immediately after being hit, with a grace period of less than 1 second. Additionally, there is a "Time Orb" system which affects the story/score, as well as a gauge which tracks how human/youkai (normal/focused) you are and determines how you can collect more time orbs.

Shuumatsu (Weekend) features a heavy rebalancing of the rates for dropped items and Satori's Learning, changes some of the recipes (with the most notable one being the recipe for the Kusanagi, which now only requires 5 Iron as opposed to 30), removes the feature that made you lose all of your "unsaved" items after getting wiped out in a dungeon, and adds a few new things such as a mini-map and an easy mode you can toggle on or off whenever you want. On easy mode, you deal more damage, take less damage, your status effects have a higher chance to work and the experience penalty on killing enemies at a lower level is reduced. You can also now refight the final boss whenever you want during the expansion, which means that Kagami's Hyper Fang Crush is no longer permanently missable and can be learned by Satori whenever you want.
