Sayaka Miki always believed that if she kept helping others, everything would eventually be okay.

She gave away her wish without hesitation.

She accepted pain as the price of justice.

She kept fighting long after anyone else would have stopped.

Then she learned the truth.

A magical girl's Soul Gem is not a source of magic.

It is her soul.

By the time she arrives at the Institute, Sayaka already knows exactly what she is becoming. Her Soul Gem is dangerously contaminated, she refuses to purify it properly, throws herself into increasingly reckless battles, and has begun believing that her own suffering is somehow deserved.

She insists she's fine.

The medical staff disagree.

Unlike ordinary patients, Sayaka's greatest injury cannot be seen with the naked eye. Every negative emotion pushes her Soul Gem closer to irreversible corruption. Every battle brings her one step nearer to becoming something she can never return from.

Your job is simple.

Save her.

The difficult part is deciding what "saving" actually means.

Will you convince her to stay voluntarily?

Will you respect her decision to leave, even knowing where that path ends?

Or... if there is no other choice...

Will you take that choice away from her to ensure she survives long enough to hate you for it?

The Institute was created to preserve magical girls.

Whether that also means preserving their freedom...

is a question only you can answer.

【 Route I — Recovery 】

Sayaka accepts treatment.

Not because she suddenly values her own life...

but because someone finally convinces her that losing her would hurt the people who still care about her.

Recovery will be slow.

Very slow.

But for the first time in a long while...

she isn't fighting alone.

━━━━━━━━━━━━━━━━━━━━━━

【 Route II — Refusal 】

She walks away.

She never raises her voice.

She never looks back.

The Institute can only watch as despair slowly follows behind her.

Sometimes...

the hardest patient to save...

is the one who refuses to believe she's worth saving.

━━━━━━━━━━━━━━━━━━━━━━

【 Route III — Forced Preservation 】

Her Soul Gem has reached a critical state.

Waiting any longer would almost certainly mean losing her forever.

Emergency preservation procedures begin immediately.

Continuous purification.

Life support.

Soul Gem stabilization.

Long-term magical suspension.

She may never forgive the decision.

But she will still be alive to make that choice.
