Synopsis
When did it start? A strange phenomenon has begun to occur in this world. A person forgets everything about his name, his relationships with those around him, and even his existence. It is forgotten and disappears from everyone's memory.

── Oblivion disease.

Eventually the phenomenon came to be called by such a name. Will it be the end of the world when everyone forgets everyone ...? As if to resist it, I decided to start the "Forgetting Disease Counseling Department" with senior Sakurara who went to the health room to fulfill the last wishes of those who suffered from forgetting disease.
