Farewell Umihara Kawase from Agatsuma Entertainment has brand new characters and no we’re not talking about adult Umihara Kawase who was revealed last time. Famitsu has an article that introduced Yokoyama, an undercover time police officer from the future who is a descendant from the Kawase family. Yokoyama has a unique ability to slow the stream of time.
Emiko-chan, a nine year old girl who is friends with young Umihara Kawase, is another playable character. She sounds like an "easy mode" character since her special ability lets players restart a level from a checkpoint if they touch it.
Farewell Umihara Kawase is slated for release this summer in Japan.
