Ushinawareta Mirai o Motomete – Walkthrough & Guide

Ushinawareta Mirai o Motomete (also known as In Search of the Lost Future or Waremete) by Trumple includes routes for four heroines, each with at least two endings. There is an enforced route order and unlock requirements.

Please note that this visual novel is only officially available in Japanese at the time of writing. This guide will tell you about the choices to access the various routes.

Purchasing

Ushinawareta Mirai o Motomete is available digitally via DMM which may not be accessible from your location and requires VPN usage to run if not located in Japan due to DRM.

You can also buy it physically using import services such as ZenMarket or if you happen to be visiting Japan, you may be interested in our guide on where to buy visual novels in Japan.

At the time of posting, physical copies can be found cheaper than buying via DMM, even counting import and delivery fees.

Running Japanese Games/Visual Novels

Many Japanese games and visual novels won’t run on non-Japanese PCs natively. You can use Locale Emulator to run these and LEShortcut to create a convenient shortcut, which you can find out how to use here.

Authentication Failed Error

If you have installed the physical version of Ushinawareta Mirai o Motomete, you may get an Authentication Failed/Kernal 32 module error message if you are using a recent version of Windows.

An unofficial solution is to download Win8WOH.zip and copy version.dll into the game install folder with 失われた未来を求めて.exe. As this is unofficial, use this at your own risk. If you are using an unofficial language patch, it may come with this included already.

Routes and Structure

Ushinawareta Mirai o Motomete has an enforced route order. You need to complete Kaori > Airi > Nagisa > Yui > YUI,S. Check the individual route walkthroughs below for further details.

Some steps in the walkthroughs below may not be typical for a heroine route. These are to collect CGs or to unlock the final route, so please follow them carefully.
