Should You Pull?
If your arsenal is missing a surefire Solo-target nuke, could use some extra Agility and Accuracy buffs or Freeze anomalies, or if your needs require a high-tech maid, Servant can take a small break from the Lunar War to serve you well. As always, do note that this is an Ultra Festival banner (UFES), meaning the Friend in question will require 250 pulls to spark and Divine Paper Dolls to Limit Break if dupes are not an option. She will only be available for the banner runtime, so either snag her now or wait for a future rerun.
Sakuya Izayoi (Lunar War Servant)
Sakuya Izayoi has always held a large debt toward her mistress, Remilia Scarlet, for taking her in and allowing her to serve as head maid in the Scarlet Devil Mansion. Her time manipulating powers were always unique compared to the youkai she lived with, something she somewhat took for granted until the events of the world of B3 sealed all of their powers. Now she was no different from the sealed mikos and magician that were her current allies- until obtaining a new set of cyber knives and accessories. With the combined powers of the mansion’s residents resonating from within her new suit, she can carry out duties at even quicker times than before. And for a maid that could already manipulate time, that’s pretty fast.
Her knives, the essential ingredient for all of her previous attacks, are now imbued with a heavy chill, perfect for slowing targets’ movements. Her first passive, Flash-Freeze Paper Knives, starts the wave off with giving one target a Freeze anomaly, which is not incredible on its own but definitely more helpful than other passives. To follow up, both of Servant’s spells, Scarred Soul: Soul Sculpture and Light Speed: C. Ricochet, target all the opponents and inflict another Freeze anomaly while applying an extra barrier of Freeze to the targeted individual. With the proper order of actions (since the spells’ Freeze anomalies last 2 turns while the passive lasts for 3), one enemy can have 5 Freeze barriers applied at once, the perfect victim for another Friend capable of breaking those anomalies.
Not that Sakuya herself is lacking in elemental breaks either. Her Focus shot, Magic Star Sword, contains a Moon break at 0P whenever the need for spamming Moon is required. Additionally, her two spells include a decent mix of Moon and Metal breaks, even if not every bullet is an element. Light Speed: C. Ricochet is especially notable, having 2 Metal breaks upon boosting twice. This would usually be a detriment for any other Friend, but Servant is always prepared to serve and can build up Spirit Power rapidly thanks to all of her skills and her third passive, Vampire Legacy.
The best servant can care for themselves as well as others, the latter of which Sakuya has many options for. module[Hobgoblin] and module[Fairy_Maid] sum up for a total of 5 levels of Agility UP for all allies, with module[Tupai] doing 3 levels of Accuracy UP. Even while sealed, her ability to manipulate time lets each Boost raise the party’s Accuracy and Graze raise the party’s Agility. It is true that some allies do just fine with their own Accuracy buffs and Agility buffs (especially on better Slicing-based characters), but Servant is always an option for providing a large assist, especially when against more evasive opponents.
To finish off, Sakuya unleashes her entire knives collection during the properly-named Cosmopolitan Museum. With a final 3 levels of Agility UP (which when combined with her other abilities, allows her to max out her Agility with 10 levels) and 4 Yang ATK UP, Servant puts those Agility buffs to good use with heavy Slicing scaling. Considering how heavily she has buffed her Accuracy from the start, there is little doubt that many of these knives will connect. Oh, and 3 extra Freeze barriers are applied to the target for good measure. Of course, the main detriment is this knife collection can only be shown to one target, meaning Sakuya is locked out of using her Last Word for convenient All-target farming.
This still doesn’t make her a bad farmer whatsoever, as she has some of the heaviest Solo-target damage in the game. Furthermore, her spell cards are strong on their own, so much that she can farm the final Hifuu LostWord Chapter 1 stage without any Limit Breaks, making her a great and efficient farm for that specific situation. And her wide array of buffs and abilities makes her far from being only situational. Servant might have a very busy schedule, but don’t let that stop you from recruiting one of the most flexible units for harder fights in the game.
*Note: As a UFES Servant, Sakuya cannot be strengthened by normal paper dolls, but rather requires either Divine Dolls or duplicates instead. Divine Dolls can be obtained via login bonuses, Scarlet Devil Tower rewards, the shop, campaigns, and special gifts.
