Menma Variation of Uzumaki

If a namikaze uses reaper death seal on an uzumaki they become menma. Similar to how uchihas become obito when hatake steals their eye. You could tweak their rasengan, give them Dark Kyuubi Chakra Mode but they cant get Sage Mode. Instead they could get 1 regular sharingan but not ms. Their Dark Kyuubi cannot be stolen.

-Game Secret
Menmas don't get Ashura Mode. Instead they get Nine Mask Awakening which grants the user nine masked beasts summoning.
Not exactly sure how masked beast controls would work. It could be a mixture of  summoning heart demons and using six paths. You can either manipulate the masked beast like a puppet or use it as a body.
