The "Clock" skill unequips an opponent's shoes for a short period of time. Several NPCs reference Cinderella when they make use of the skill — opponents Bobo, Timi, and Mela directly reference "Cinderella's crystal shoes" when they use the Clock skill against the player. Additionally, the "Clock" attack can be rebuffed by using the "Cinderella" skill, which redirects the attack towards the one who first cast it.

The Chapter 2 side quests reveal that the theater troupe working next door to the December Troupe is putting on a play called "Romeo and Cinderella." It provides the impetus for collecting parts of the "Troupe * Romeo" set, which seem to represent the costume the lead would have worn, if he'd been present to compete with Nikki. The title "Romeo and Cinderella" may also be a reference to the well-known Vocaloid song of the same name by doriko.
"Romeo" - a short blond wig with the description "Quiet! What's that light coming through the window? It's the east! Juliet is the sun!" A loose translation of Romeo's famous speech as Juliet appears on her balcony in Act 2, Scene 2.
But, soft! what light through yonder window breaks?
It is the east, and Juliet is the sun.
"Childe" - a shirt and tabard tied with a sash, with the description "Love is a cloud of smoke blown by a sigh; it purifies the embers in lover's eyes and arouses waves in lover's tears." This is a loose translation of a monologue done by Romeo in conversation with Benvolio during Act 1, Scene 1:
Love is a smoke raised with the fume of sighs;
Being purged, a fire sparkling in lovers' eyes;
Being vexed, a sea nourished with loving tears.
"Montague Prince" - a half cape tied off with elaborate cording. The description reads "I'd rather die of my enemy's sword than live in pain without your love."
"Noble Childe" - Plain grey leggings to go under the tabard, with a description reading "The lover's voice is so gentle in the night It sounds like the most delicate music!" Another loose translation of Romeo's lines from Act 2, Scene 2:
How silver-sweet sound lovers' tongues by night,
Like softest music to attending ears!
"Warrior" - tall brown boots with more gold cording. The description reads "If you were out in a faraway seaside, I would run the risk to search for you." Also from Romeo's dialogue in Act 2, Scene 2:
I am no pilot; yet, wert thou as far
As that vast shore wash'd with the farthest sea,
I would adventure for such merchandise.
"Rose" - a romantic red rose held in the mouth. The description reads "I swear I will give my entire life to you and follow you no matter where you go."
In story 4-5, Momo calls Toto's newest boyfriend "totally a carbon copy of Christian Gray."
Lunar's "Clock" quote (when she uses the skill that temporarily disables Nikki's shoes and lowers her score) states that Cloud Empire people think "small feet" are beautiful. This is a reference to Imperial China's foot binding tradition.note (Warning: there are some pictures of bound "lotus feet" and they're not exactly pretty)
The hairstyle for the Assassin's Faith outfit is short, wavy, red, and called "Natasha."
