lol, I just put those three cards through the Google Chrome translator, and it calls them the "The Three Musketeers of Chaos"
trying to work out what Chrome's translation is still certainly interesting, so I put this together for fun. Anyone who actually knows a bit of japanese is welcome to improve on this

Annarose: Triad of Chaos (or three musketeers of chaos of you prefer

)
Lvl 8 HP 80 AT 40 DF 0 AGI 4 RNG 2 LP1
Soul: Arrow of Chaos (0SP)
subtract 50 dmg to three random enemy units. "The Raibaruikusa [SP] 2 Yasu Masu" (can't work out what this bit means, possibly give the opponent 2 SP)
Trait: The True Beauty of Chaos
This unit is treated as [Nemudokado]. (New unit type?)
Open: Spirit of Division (0SP)
If player's SP is 6 (guessing here) then your units gain [At +40]. you cannot set a card for 3 turns.
(there's a lot I can't understand, but this is what the general gist of it sounds like)
Close: Playing Soul (0SP)
Return this card to the file. You loose 1 LP
Zalzagul: Triad of Chaos
Lvl 7 HP 50 AT 80 DF 20 AGI 3 RNG 3 LP1
Soul: Knight of the Triad (3SP)
[Conditional/ Impact?: One to five random units are sent to the cemetary
(I'm really not sure on this but if I'm not that's just broken. Also depends on what "Impact" is supposed to mean)
Trait: Crystal Abyss
While on the field, this unit is immune to Open skills and Soul Skills
Start: Hammer of the Strong (0SP)
set 1 allied unit to [HP = 0]. One random enemy unit is dealt [Damage: first chosen unit's lvl x 20] You gain 0SP next turn.
Action: (untranslated symbol) I from Hell (0SP)
target closed unit is sent to the cemetary, the player that owned the unit gains SP equal to the unit lvl.
Galdirea: Triad of Chaos
Lvl 7 HP 80 AT 40 DF 0 AGI 2 RNG 5 LP2
Soul: Hand Hell (SP0)
One random enemy unit gains Max HP =30, HP=30, AT=0, DF=0
Open: Curse of the Profound (SP1)
All of your units gain Max HP=30, HP=30, AT=30, DF=0, AGI=2, RNG=2
Action: Black Rot Hand (SP1)
One random unit in range is sent to the cemetary. "The Raibaruikusa [SP] to [the unit chosen LV] increased"
(probably opponent gains SP equal to unit's lvl, but I'm not sure what Raibaruikusa could mean.)
