Who Is Keiko? (Based on Fragmentary Descriptions)

From scattered playthrough logs and a single archived screenshot (Japanese, dated 2006), Keiko is described as:

• The “quiet observer” of the five girls – not the childhood friend or the tsundere, but a soft-spoken classmate who works part-time at an aquarium.
• Her “Another Day” episode involves her disappearing after the S.O.S. signal is traced to an underwater communications array. Unlike the other girls’ lighthearted beach episodes, Keiko’s route leans into psychological mystery: time loops, recorded messages from a future that never happened, and a choice to “let the wave take you back.”
• The title “SOS” becomes literal in her ending – the protagonist must decide whether to answer Keiko’s final transmission or erase the signal entirely.

Inciting Incident: The Unseen Call

• Most students ignore the message, assuming it’s a prank. Keiko, however, feels a strange tug of responsibility—she’s the only one who heard the transmission clearly.
• She decides to investigate, taking notes in her sketchbook to track any clues.

The Girl from the Train

On the commute, Keiko notices a girl with a chipped red umbrella who stares at the window with the kind of intensity Keiko remembers from her teenage years. The girl’s expression nudges Keiko into an unguarded memory of rain-soaked summers and a first impulsive kiss on a station platform. That recollection blooms into a longer flashback: late-night roof-top parties, whispered confessions, and the indelible image of a friend who left without goodbye. Keiko carries the image through the day, tasting both nostalgia and a dull ache.

Midday — The Café and the Map of Small Griefs

At the café where Keiko sometimes writes, she meets Aya and Minori. The three women occupy a corner table like a small council. Aya is pragmatic, listing job possibilities and logistical details about moving in with a partner. Minori jokes to mask a tremor of worry about her elderly father’s health. Keiko reads their voices like a map of small, differing griefs. Conversation drifts from landlord disputes to the ethics of re-gifting; it touches on the letter at Keiko’s table without naming it.

Aya brings up a mutual friend—Sora—who's been posting bright, polished photos online that don’t match the faint messages Keiko has received. The discrepancy sparks a debate about curated selves versus messy lives. Keiko thinks of the red umbrella girl, of how people present versions of themselves for convenience or protection.
