Sekai no Subete, developed by Tama-soft, was originally released on March 26th, 2002 in Japan. It also received many ports thanks to the work of Regista. Now there’s a remake by Tamaoka-Soft available on DLsite.
Hiroshi returned to his hometown after 8 years in Tokyo trying to attain his childhood dream and failing to do so. Feeling powerless and lacking support from his family, he could only think about giving up. He felt that a poor student like him was unneeded and there was no longer any place for him. That was before he met Tomoko at the light music club and realized that he was not the only one in the same situation.Official description
