Quick unlock answer
Community route: follow Haruhi’s Tourist repairs, choose the distrust-of-the-courier response, invite Haruhi when offered, then finish the remaining repair and conversation. Check Melancholy in Steam. Keep saves before the trust dialogue and invitation; a separate guest branch is a precaution, not proof that Haruhi and Baketsu cannot coexist.
Guest overlap: current advice and unresolved reports
The community guide’s Baketsu text warns against other guests; its August 30 comment reports Haruhi and Baketsu together, with Kaito separate. Use separate branches as a conservative retry plan. Haruhi/Baketsu exclusivity remains unresolved, not a mandatory rule.
Reported route steps
Before the Tourist/Haruhi hand-in conversation, keep Checkpoint A. The Steam community guide describes telling Haruhi that you do not trust the courier. Follow that meaning in your game’s language; the site has not isolated this answer as a universally necessary trigger.
Keep Checkpoint B before the invitation, then invite Haruhi when the option appears. A separate branch makes retries easier; it is not an established requirement to exclude Baketsu. Keep Kaito comparisons on another branch while testing this route.
After the invitation, complete Haruhi’s remaining repair requests and speak to her after the last repair. Let the conversation finish, then check Melancholy in Steam. A browser checklist tick is not an unlock confirmation.
Why two checkpoints matter
Save A before the trust conversation; save B before the invitation. Keep both until the Steam result is known, so a late retry does not erase the earlier choice.
Common route failures
Check unfinished Tourist work and the conversation after the last repair first. Retry from Checkpoint B without overwriting the original; if needed, compare the earlier trust response from Checkpoint A. An existing Baketsu invitation alone does not prove this save is invalid. Record the build and failed stage if the Steam achievement stays locked.
Use the complete achievement hub
Return to All 50 ReStory Achievements to find another missing achievement, plan a protected route, or continue the browser-only manual checklist.
Media and evidence boundary
Before retrying, check Steam’s achievement list after the last Haruhi conversation. If Melancholy is still locked, keep both checkpoints and compare the last unfinished repair or dialogue. The linked source documents the route; ordinary character artwork cannot establish an unlock.
