Secret of the Cursed Mask

Inuyasha: Secret of the Cursed Mask is a PS2 Role PLaying Game that appeared in both Japan and America. It allows the player to choose which gender their character will have. Roughly it should take place some time prior to Naraku's fleeing to Mount Hakurei, or after, while he's still on the run.

A dececent of Utsugi and Kakuju, the player holds the latent ability to command Shikigami, which is awakened during the journey. While spending time with Inuyasha's group the player may either form a strong freindship with those of the same gender (and Shippo), or start a romantic triangle (or just add onto an already messy one).

Utsugi

After being chased out of the village because of not aging, Utsugi teamed up with Naraku to obtain a decendent from the future (the player) and a shared of the Shikon Jewel, in the hopes of perfroming Soul Infusion to become a true human once more.

Kakuju
The former preist or preistess of the Kururugi Shrine. Kakuju sought to reclaim his lost love in the form of a Hitogata, a plan that backfired when Utsugi did not age after many decades.
