Ooku Tokugawa Restoration Labyrinth Rerun Should You Roll?
As usual, this is just my 2 cents on each servant. Whether or not you choose to roll regardless of my opinion is up to you. Do note that I will only be discussing the LIMITED servants for this event and not the General Pool or Story Locked Servants.

1. Kama

Kama is an ST Quick Assassin. Kama is one of the best DPS/Nuke Servants in the entire game. Her kit is simple to understand and extremely powerful. Kama's NP does significant damage and can generate a decent number of C Stars and NP thanks to its high hit count. It is also basically guaranteed to Charm the target so long as they don't have some kind of resistance to Charm. The fact that her NP automatically gets a Quick Card buff is also nice. Her skills also provide her with powerful ATK Buffs, 50% NP Battery Guts, Heals, Overcharge Up and Crit DMG Buffs which make her exceptionally good at tenderising enemies. Lastly, she is also one of the only Servants to have true class advantage to Alter Egos thanks to her 3rd Skill. Overall, excellent, especially if you have Skadi.
2. Sessyoin Kiara

Kiara is an AOE Arts Alter Ego. She is by far one of the best farmers in the game. She has an AOE arts NP that is unblockable that's to its inherent DEF ignore and her Invul Pierce Skill. Her 50% NP Battery and decent Buffs from her skills allow her to kill most under 100k Cavalry enemies with ease. With that said, outside of farming, Kiara is pretty much useless.
I hope this was helpful and bid thee Masters good luck in rolling.
