Seireitou Gaiden

The Seireitou Gaiden (リやんガいでん, Seireitou Sidestory) is a four part trilogy that takes place in the early years of Seireitou Kawahiru's childhood: more than a decade before Naruto and Naruto Shippuden.

The story surrounds a four-year old Seireitou Kawahiru, who is an orphan in the starting periods of the Third Great Shinobi War; which lasted for over 10 years. It gives readers a glimpse into the famous Yonkou's past and childhood, as well as providing an answer as to how he obtains his Rinnegan and meets Shiori Miyamoto. It also shows us how he meets the other three, soon to be, Yonkou.
