i had the same problem too. ever since the v4.0 update UT speed training has been undefeatable. -_-

i also asked others about this but they also said to meet the required initiative -_-.

my training was in 5.3k initiative and just got lucky last week by using hinata -_-.

man that chojuro's attacks are so OP.

PS. im in 70k BP and 3.7k initiative i guess?
