Harukanaru Toki no Naka de 4 (Treasure Box)

Released in Japan on June 19, 2008, Harukanaru Toki no Naka de 4 is a romantic adventure and turn-based RPG developed by Ruby Party for the PlayStation 2. As the first prequel in the Haruka series, the story follows Chihiro Ashihara, a high school student who discovers she is actually a princess of the fallen kingdom of Nakatsu Kuni and is summoned back to a parallel world inspired by ancient Japanese and Indian mythology. 

The elite Treasure Box edition is a collector's set that includes the game alongside several luxury items: an analog clock featuring recorded voices from the eight main male characters, a comprehensive illustration book by series artist Tohko Mizuno with voice actor signatures, a voice actor commentary CD, and a special drama CD detailing a "what-if" modern-day scenario. This edition is highly valued for its deep lore dive and unique physical collectibles that bridge the gap between the game's fantasy setting and the real world.
