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.
