She wears the default 1980s uniform with black, knee-length socks. Unlike the other rivals, she is shown wearing the 1980s buruma (gym uniform) in her official artwork.

According to Ryoba, Sumiko is fit, tan, and has toned abs.

Personality

She's extremely serious about eating healthy and getting lots of exercise.
Known to go to great lengths to attempt to convince others to adopt her own lifestyle choices.

— Description from Official Website.

A sporty girl who is training hard to be a career athlete. Very serious about eating healthy and getting lots of exercise.

— Description in Ryoba's notebook.

Sumiko's reaction to a camera.

Among the Personas that are currently implemented in the game, Sumiko is Lovestruck. If she witnesses Ryoba Aishi commit murder, she will run to Jokichi Yudasei and inform him that Ryoba is a murderer, causing an automatic Game Over. If she encounters a corpse, she will run to Jokichi and tell him there was a murder in Akademi. The two will then run out of school and call the police.

If she is eliminated peacefully, Sumiko will use the Heroic persona in subsequent weeks.

As seen during her matchmaking, Sumiko doesn't appreciate more "usual" compliments like "you look nice". However, this attitude has limits, as Sumiko has grudges against the Evil Photographer. Because she's really serious about eating healthy, she won't accept any snacks offered by Ryoba.

According to YandereDev, Sumiko is competitive.

Her black knee socks represent her superiority complex and tendency to force her habits onto her peers.

Introduction

In the introduction cutscene following Honami Hodoshima's elimination, Ryoba elaborates on her new rival as a picture of Sumiko is shown.

My Senpai is perfect in every way...
He's smart... talented... handsome...
...so I suppose I shouldn't be surprised that another girl has fallen for him.
This one is an aspiring athlete.
Fit. Tan. Toned abs.
Boys go crazy for that type of girl, don't they?
She worries me. I'll need to take her out quickly.
She seems to be encouraging my Senpai to adopt her lifestyle choices...
Eat healthy. Exercise often. No smoking or drinking.
Of course, all of these are respectable decisions...
...but she's actually putting her health in grave danger...
...by getting between me and the man I love.
I heard that she prepares a special meal in the Home Ec room every day.
A healthy, nutritious meal packed full of vitamins and minerals.
I hope she chokes on it.

— Ryoba's monologue about Sumiko.

Events

Monday

At 7:00 AM, Sumiko gives Jokichi a bento, determined to convince him that healthy food can taste good. They agree to meet at 5:15 PM so he can tell her how it tasted. At 5:15 PM, Jokichi and Sumiko follow through with their plan and meet outside the gate. If the bento wasn't poisoned with an emetic poison, Jokichi says he enjoys it, and Sumiko vows to make him forget about junk food. They will then jog home together. If the bento was poisoned, Jokichi says that the bento made him sick, and they walk home separately.

Tuesday

At 7:00 AM, Jokichi gives Sumiko a book she had asked about, and she puts it in her bookbag. They decide to meet at 5:15 PM so she can return the book. At 5:15 PM, Jokichi and Sumiko meet outside the gate, and Jokichi asks her what she thought of it. If the book wasn't stolen, Sumiko says it's probably interesting, but she couldn't enjoy it due to disliking not moving for long periods before giving it back. They then jog home together. If the book was stolen, Sumiko apologizes for losing it, and they walk home separately.

Wednesday

At 7:00 AM, Sumiko tells Jokichi she has a gift for him, which she'll give to him at lunchtime. She leaves the gift on her desk when she goes to drop off her bag. At 1:00 PM, Sumiko and Jokichi meet on the Rooftop, where she gives him the gift box. If the contents weren't replaced with contraband, the box will contain a book on healthy eating, as Jokichi was "getting tubby". They then eat lunch together. If the contents were replaced, Jokichi will refuse the gift, leaving Sumiko to eat lunch alone.

Thursday

At 7:00 AM, Sumiko and Jokichi talk about a movie they're planning to see after school. During this conversation, Sumiko yawns, and Jokichi suggests she take a nap after cleaning time so she won't sleep through the movie. At 4:00 PM, she takes a nap in the Infirmary. If her bento wasn't poisoned with a Sedative, Sumiko meets Jokichi at the gate at 5:15 PM, and they leave school to see the movie. If her bento was poisoned, Jokichi will get impatient and go home at 5:55 PM.

Friday

At 7:00 AM, Sumiko has a conversation with Jokichi. During this conversation, Jokichi will tell her that he is worried about a test that they will have before lunch, as he lost all of the notes he took and was unable to study beforehand. Sumiko copies her notes for him and leaves them on his desk. At 1:00 PM, Sumiko and Jokichi will meet on the roof, and she will ask him if the notes helped. If the notes weren't sabotaged, Jokichi says he aced the test, and they eat lunch together. If the notes were sabotaged, Jokichi says the notes didn't help him at all, and they eat lunch separately.

At 5:00 PM, Sumiko will go to Jokichi's locker and leave a note asking him to meet her under the cherry tree behind the school. If Ryoba Aishi matchmakes her, she will go to Kagemori Takagi's locker instead. Sumiko will then run to the Confession Tree and wait for either Jokichi or Kagemori. She will then confess her love to him. If she confesses to Jokichi, he will either accept her feelings or reject them, depending on whether their events were sabotaged. If she confesses to Kagemori, he will accept her feelings.
