This file is developer's official patch.
Please copy "monmusu_fight_olb.exe", "monmusu_fight_olb.kgt",
that are put in each folder, to the folder in which "monmusu_fight_allages.exe" is installed.

* Attention about this patch *
If players' "D_title.demo" is not the same thing, there is a possibility of synchronization shift.
If you had a patch in DLsite, you think you overwrote "D_title.demo", so you may have to download the game again from Steam.
Please respond to situations such as renaming according to the situation of the player.

We use an external tool called "LilithPort" for online matches.
This software is widely used as a modified version of MTSP.

*Attention*
The first story such as "Version 1.5" is irrelevant to MONMUSU * FIGHT so you can ignore it.
