The purpose is to defeat `Naraku` and collect the scattered `Soul of the Four Souls`, but you can continue to collect `Four Soul Fragments` after clearing. There are also original movies only for games produced by Sunrise. A special `Inuyasha notebook` was added as a first-time benefit. Inuyasha becomes a human and weakens on the day of the new day (new moon) due to the age setting. After clearing the Maitreya, the air holes cannot be used.
