Gloom: Abilities revolve around manipulating emotions as you'd guess (which is funny, since I had this thought long before Hata no Kokoro was created for Touhou), but due to this not working on the other components, she's generally considered the weakest of the components. This is literally all I have on her: Nothing on personality, nothing on how she fights in battle, nothing...she's the least developed outside of Pandora thus far. Is antagonistic towards Parsee and Momiji.
During the optional boss fight with Gloom Complete, she changes her strategy a bit and utilizes her Illusionist abilities more, creating illusions of characters in the current party that uses the same abilities as the original party members. Damaging any of these illusions will also damage the original as well. Defeating Gloom will also defeat the illusions.
Guadians: Ice/King Behemoth,
?, Zodiark
Class: Puppetmaster/Illusionist
Real name: Zenia
Height: 5'5"
Pestilence: Abilities revolve around manipulating diseases, as you'd expect. Unlike what you'd expect from someone like Death or Gloom, Pestilence, while appearing serene and calm, is a bit sadistic in nature (she doesn't really show that very often though). In-battle, she deals with a multitude of statuses, including of rare status effects such as Curse, Heat, Full Break, and Venom. She wields the spear Ame-no-nuhoko (which is an actual mythological spear). Is antagonistic towards Yuuka. Limit Break is Diseased Tempest.
During the optional boss fight with Pestilence Complete, the party will be inflicted with various statuses in a set order, starting at level 1 statuses and continuing up to level 10 statuses of varying degrees. These bypasses all innate immunities as well as equipment immunities, so the fight is pretty much a timed fight. Pestilence otherwise is pretty much the same as normal.
Guardians: Marquis Malboro, Beezlebub, Astroth, Cerberus
Class: Ark Knight
Real Name: Kallisto
Height: 5'8"
Death: Abilities revolve around manipulating life and death, as you'd expect. However, Death is generally the most calm and honorable of the components, not using her abilities very often even though she has the chance to do so many times throughout the story. However, holds a grudge against Order due to how often Order has backstabbed her, and is generally seen often with Pestilence. In-battle, she deals with instant death as well as many of the generic statuses (in essence, she's like how Komachi is in the story). Is antagonistic towards Komachi. Wields the scythe Yomotsugama Izanami. Limit Break is Apocalypse.
During the optional boss fight with Death Complete, Death will start a time limit on a specific character, and once time is up, the character is permanently killed and unable to be brought back at all (the character is outright removed from the fight and unable to be brought back via Hope's Return spell). Death otherwise is the same as usual pretty much.
Guardians: Iron Giant, Omega Weapon, Ozma, Hades
Class: Time Mage/Necromaner
Real Name: Thana
Height: 6'1"
Fate: Abilities revolve around manipulation of fate obviously. Fate is happy-go-lucky and fun-loving, but can be deathly serious when the need arises. While she can manipulate fate, she only does so to a degree, as her abilities cannot extend to anything related to the Pandora's Box. Is antagonistic towards nobody but Order and Chaos, and is generally friendly with Hope. In-battle, her abilities revolve around mid-level elemental spells as well as mid-level statuses (basically, she's a jack-of-all-trades master-of-none type character). Does not actually wield any weapons at all. Limit Break is Cosmic Spear.
During the optional boss fight with Fate Complete, Fate will attempt to counter specific commands used by various party members with powerful abilities, making it hard to judge which abilities to use at which times. In addition, Fate no longer uses her elemental skillset that she originally has and instead starts using the more powerful Predict skillset (similar to what Shikieiki's skillset is).
Guardians: Exodus, Adrammelech, Ultima
Class: Oracle
Real Name: Lachesis
Height: 4'9"
Hope: Abilities revolve around manipulation of light and dark. This is adversely affected by her personality: The more optimistic she is, the more light she gives off to her allies, but the more pessimistic she becomes, the more dark she ends off giving instead. This isn't really spoken of in-game yet however, but it's vaguely hinted at by Hope that she feeds off of the party's light to give strength. Is generally a sweet girl that tries to keep everyone's spirits up, but tends to fall into a depressive state due to her history of failing to stop Pandora. Is antagonistic towards Chaos and Order, but on friendly terms with Fate. Wields a staff named Khatvanga. Limit Break is Celestial Star.
Hope's full potential is unexplored outside of her ability to break all manners of mind control as well as giving more/less power depending on the amount of light that she is currently surrounded by.
Class: Seer/Cleric
Real Name: Elpis
Height: 5'1"
Chaos: Abilities revolve around utilizing the abilities of those she has defeated during the current cycle. She serves to aide whichever side of the spectrum is lowest (if light is lower than dark, she aides the light side, but if dark is lower than light, she aides the dark side). Is generally gruff and rough, and enjoys a good fight or in general beating down anyone. While she may appear sadistic, she is not and is usually just venting out her frustration or anger in this manner. Is antagonistic towards Hope, Fate, and Order, as well as Reimu. In-battle, is capable of using high-level elemental abilities (Tsunami, Hellfire, Judgment Bolt, etc.) as well as powerful abilities such as Maelstrom (reduces party's HP to 1), Graviga, and The Void (Instant Death + 9999 damage. Wields the weapon Varunastra, which is similar to Necrid's weapons in Soul Calibur II (allows her to create whatever weapon she wants at any given time). Limit Break is Cosmic Break.
During the optional boss fight with Chaos Complete, Chaos utilizes her actual skillset, ignoring all other abilities she has used in previous boss fights, and attacks much more frequently. In addition, she favors physical-based skills over magical-based skills, some of which will bypass the target's Defense stat entirely.
Guardians: Lich, Marilith, Kraken, Tiamat
Class: Berserker/Arcanist
Real Name: Ystelle
Height: 5'10"
Order: Abilities revolve around usage of high-level magic. Is egotistical and self-centered, coming with a Messiah Complex believing that returning everything to nothingness and then recreating it herself by using The Void will give perfect order to everything. Has no regards to life at all and no sense of honor, but this may all be due to her being corrupted by Pandora as Fate and Hope explain in the story. Doesn't hesitate to use anyone for her own agendas. Is antagonistic towards Chaos, Fate, Hope, Reimu, and Byakuren. In-battle, is capable of using high-level magic, such as Ultima, Meteor, and Shadow Flare. Wields the staff Kaumodaki. Limit Break is Seraphic Law.
During the optional boss fight with Order Complete, Order simply uses the highest level magic spells available.
Guardians: Omega, Yiazmat
Class: Sage
Real Name: Themis
Height: 5'10"
Pandora: Abilities are unknown at the time, but is capable of inflicting mass destruction when at full power after absorbing all of the fragments. Is bent on nothing but destruction and has no regards to life, but won't hesitate to ally herself with anyone capable of aiding her, such as Yuugenmagan. Is currently residing within Rinnosuke Morichika, using him as her vessel, but is generally surpressed by Yukari Yakumo's manipulation of borders. Is antagonistic towards most of the cast, but mostly to Reimu, Hope, Fate, Patchouli, and Sariel.
Class: Memorist
Height: N/A
