Some text has been revised
Character names were missing from dialogue lines, so I've corrected them.
I added the sentence [This choice branches the ending] at the branching choice points.

If the game fails to launch after updating
You may encounter an error message labeled 『セーブデータの移動を検知しました。信頼できるセーブデータでない場合、絶対に読み込まないでください』『起動を中止しました。セーブデータを削除して、もう一度、起動してください』preventing the game from launching.
At that time, please open the local file and delete the two files named imajinarybadfriend_sf.sav and imajinarybadfriend_tyrano_data.sav insideit.
Then it should start up. (If it still doesn't start up, please contact us via email.)
This file contains your save data, so deleting it will reset your progress to the beginning. Unfortunately, this is the only solution available due to the game's design.
We sincerely apologize for the inconvenience and thank you for your understanding.
