Itsuki Sumeragi

Itsuki Sumeragi is a girl with a height of 158 cm.

She has short, brown hair styled in a slightly wavy bob.

She often wears a headband and keeps her nails well-decorated.

Her school uniform is neat since she cares about fashion.

Itsuki is ambitious and wants to build strong connections in politics and business.

She is fascinated with gambling and has a unique, somewhat creepy hobby: collecting real fingernails from people who lose to her.

She is determined but can become very scared when truly threatened.

Initially, Itsuki tries to keep a confident image but often shows her emotions, especially when she loses or feels fear.

She is polite and uses respectful language with those older or in higher positions.

Itsuki is from a wealthy family who owns a well-known toy company in Japan.

Her father's rules are very strict and practical.

Her main goal in joining the Student Council was to secure valuable connections for her future and support her family's business.

She joined the Student Council mainly by using her financial resources and paying large "tribute funds."

If she fails to build these connections, she could be disowned by her father, even though she is his only child.

Itsuki is very good at card games, especially with cards made by her family's company.

She often cheats by using marked cards but was caught by Yumeko Jabami.

Her strength in gambling mainly comes from her access to high-quality tools and resources.

She is clever and observant but not as skilled as some top gamblers at the school.

• She was brought into the Student Council by Kaede Manyuda, and they shared some mutual respect.
• After her match with Kaede, they became closer, and she eventually cared for him when he was hurt.
• She wants to support Yumeko Jabami in the hope that Yumeko will help her return to the Student Council.
• Her relationship with her father is complicated, as he expects results and puts a lot of pressure on her.

First Confrontation with Yumeko Jabami

Itsuki challenges Yumeko Jabami to a "Double Concentration" card game, using her family's custom playing cards.

She tries to use a trick with marked cards, but Yumeko sees through it.

Yumeko raises the stakes and suggests a new penalty—betting each other's fingernails.

Afraid of ruining her family's reputation, Itsuki loses and is left begging for forgiveness.

Losing Her Place and Finding New Ambition

After her loss, Itsuki is kicked out of the Student Council.

Her dream to make important connections is crushed.

Instead of giving up, she sets a new goal: help Yumeko beat the current council, hoping to become an officer again if Yumeko wins.

Gambling Battles and Student Council Election

Itsuki helps Yumeko get tickets for big matches and ends up gambling against Kaede, where she unexpectedly wins.

She was angry with Kaede after the game but listened to Yumeko, who taught her to be more understanding and respectful.

Later, Itsuki takes care of Kaede, showing her kind side.

During the election, Itsuki joins the "Public Goods Game" with Yumeko and others.

She tricks Miroslava Honebami and wins the game.

However, she secretly loses another bet against Terano Totobami to help Kaede, losing a lot of votes and dropping out of the election.

Despite this, Itsuki considers it a personal victory.

• Itsuki often addresses upperclassmen with titles like "senpai" and shows great respect in her speech.
• She cares a lot about her appearance, especially her nails and hair accessories.
• Her unusual hobby (collecting nails) is unique and memorable among the students.
