Katie smoke (the witching hour)

Personality; Katie is the feature servant for this event and she's being quite mischievous, it's possible she may be the cause of the witching hour but it's more likely that she's just having fun while someone else pulls the strings
Event ability: the witching hour (double power in a Halloween zone, she can change people magic up more than a normal alterer)
Class: alterer
Magic: stuffed magic
Weapons: none
Hidden ability: wonderland (reality marbles superimpose stronger effects into the area they are set over)
Jack-o-all trades (she can change her class ((and stars accordingly)) whenever she wants)
Characteristics: Halloween 2019, female, magician, Japanese, American
Rank: A
Grand magic: jack-o-bear
Rank explanation: Katie is another example of a servant who is good at a lot of things but isn't a master of any of them, she has a grand magic that summons a giant monsters and her reality marbles can be useful but over all she's not as good as the servants who specialize

Kuna smoke (rosebud) (the little witch that could)

Personality: the witching hour has turned back time for kuna Turing him to a kid version of himself, he also seems more bratty now
Event ability: the little witch that could (magic damage is halved but defense and speed are doubled, power is doubled in Halloween areas)
Class: caster
Magic: fire magic, electric magic, ice magic
Weapons: little staff
Hidden ability: sweet tooth rank EX (magic is both restored and strengthened when eating candy)
Wonderland
Grand magic: little Halloween magic
Rank: A
Characteristics: male, Japanese, Halloween 2019, magician
Rank explanation: Kuna's Halloween version is a decent servant but falls into many of the pitfalls that Robin Hood does, sweet tooth just isn't that great of a hidden ability but it fits with his more defensive kit better than with robins offensive one, he can be a good defensive option but that's about it

Yumi smoke (cool and confident)

Personality: yumi has grown older after the affects of the witching hour and her own pleasure city, she is calm and confident using everything at her disposable to get what she wants, some might even call her manipulative

characteristics: female, magician, fae, kitsune, halloweeen 2019, Japanese
Grand magic: a world of boundless pleasures
Rank explanation: yumi is a master of controlling the battlefield a trait which few other Servants (most of which are events servants) can do, she can trap and destroy her opponents with her hidden abilities and then finish them off with her magic attacks which while not powered up by any hidden abilities will still finish off a weakened opponent
