Agent17 Walkthrough – v0.26.x Story & Progression Guide

Start by clearing the school, back-alley and home introduction, then use the phone and quest screen as your source of truth. Save before Fate choices and route branches.

Opening route

This sequence establishes the phone, computer and first map loops without committing to a late-game branch.

  1. 01

    Clear the school introduction

    Visit the classroom, speak with the available characters and attend class.

  2. 02

    Visit the back alley

    Speak with Erica after leaving school to advance the opening chain.

  3. 03

    Return home

    Talk with Dana, advance time and respond to every new phone topic.

  4. 04

    Set up the computer

    Follow Amber’s request, obtain the computer and sleep so the next-day triggers can appear.

  5. 05

    Check the school again

    Continue Luna’s introduction, then speak with Ophelia about the computer.

  6. 06

    Open the shopping route

    Visit Anriel at the gift shop, then continue the Makoto and Amelia conversations shown by the quest flow.

  7. 07

    Return to Dana and rest

    Finish the home conversations, use the computer and choose Rest when the phone route asks for it.

Read the map before skipping time

The city map is the hub for route timing. Character portraits on locations are a stronger signal than repeatedly advancing the clock.

This is an editorial order for reducing cross-route blockers, not a claim that Agent17 has only one correct path.

Character routes

06

When a quest will not advance

Wrong time segment

Check morning, daytime, evening and late-night variants before repeating a location.

Hidden prerequisite

Another character, skill, purchased item or message may need to complete first.

Route state changed

A Fate choice or imported save can move the character into a different branch. Load your pre-choice save to compare.

Old guide mismatch

v0.25 steps may not match the v0.26 map, inventory or new systems.

Patch-specific bug

Use v0.26.10; v0.26.11 was withdrawn, and earlier v0.26 patches carried known blockers.

Missing save backup

Stop experimenting on the only copy. Duplicate the save before console tools or external editors.

Agent17 redemption or corruption Fate choice screen
Game reference

Fate choices can change later route state. Use named manual saves rather than relying only on autosave.

08

Walkthrough boundary

This guide keeps descriptions non-explicit and focuses on tasks, prerequisites, items, puzzles and irreversible choices. It does not reproduce scenes or distribute save files.

The current stable file is v0.26.10, while the broadest indexed community walkthrough is labeled v0.26.9. The final patch mainly adds balance and bug fixes, so route steps are used with a version note rather than silently presented as identical.

Quick answers

Frequently asked questions

What should I do first in Agent17?

Clear the school introduction, visit Erica in the back alley, return home to Dana, respond to the phone topics and obtain the computer.

Why is a character not at the location?

Check the time segment, active quest text, prerequisite item and linked character route before skipping another day.

Does this walkthrough cover v0.26.10?

It is organized for the v0.26.x route structure and flags where the most detailed community sequence is labeled v0.26.9.

Should I use cheats to fix a stuck quest?

First check version, prerequisites and a clean save. Console or modified-build changes can create harder-to-diagnose state problems.
