Beat Blades Haruka is an eroge developed by Alice Soft, about a student Ikusabe Takamaru living an ordinary school life, seeking romances which are constantly interfered by Shihoudou Narika (the daughter of his apartment manager). After falling in love with a transfer student Takamori Haruka, on the same night the two become pursued by a group of mysterious ninja. Just when they thought all hope is lost, Haruka appeared in kunoichi ("female ninja") attire. Then the ero-stuff begins... The game is considered to be the successor of Beat Angel Escalayer, another eroge by Alice Soft.
