Harukanaru Toki no Naka de

On the first day of a new school term, high school student Akane Motomiya, her classmate Tenma Morimura, and their underclass friend Shimon Nagareyama are sucked into a mysterious old well. When they awake, they are in Kyō, another world that resembles Kyoto during the Heian Period. According to the young scion of the Star Clan, Fujihime, Akane is the Ryūjin no Miko, who has come to save Kyō from the ambitions of the Oni Clan. In this task, the Akane has the help of eight men known as the Hachiyō, and her friends Tenma and Shimon number among them. Initially, Akane is bewildered by her new circumstances, but she gradually comes to face up to her own destiny and understand the world of Kyō.

Harukanaru Toki no Naka de places the player in the role of a girl who is surrounded by attractive young men, and gives her the option of trying to win the heart of one and live happily ever after. The heroine must also fight evil with the help of the attractive young men. The result is a hybrid game with a visual novel–like interaction mode, a simple role-playing video game battle mode, and a board game–like map. Haruka is made up of ten chapters, eight of which involve the core gameplay. These chapters take place over a two-week period and involve traveling around the Kyō map, searching for various key items. Kyō is made up of roughly 20 areas and it is possible to visit three in one day. However, most areas are possessed by onryō (怨霊) vengeful ghosts that must be dispelled before you can enter, and fighting them consumes one of the three visit chances. Haruka's battle system is limited in comparison to most CRPGs of its day. The maximum party size is 3 characters, but only Akane is under the direct control of the player. Though Akane can attack and defend, her other abilities – the use of healing items and spells, and the ability to encourage her comrades, are more useful. There is no magic point system as such. Casting spells is based on the morale of the Hachiyō members and the number of elemental fuda (札) cards Akane has. Furthermore, there is no experience system and the character's hit points are refilled automatically between fights. The main reward for fighting, besides gaining entrance to a given area, is the chance to gain the trust of Hachiyō. The greater a Hachiyō member's rapport with Akane, the more effective he will be in battle.
