Reasons why Boruto's "dojutsu" has NOthing to do with Tenseigan!

Do you think Boruto and Mitsuki, mates of the same team, will have identical "unicorn" modes???

You didn't answer how come Boruto can jump to the Tenseingan despite having NO byakugan up to now?? Madara didn't jump right away to the Rinnegan without awakening the Sharingan and Mangekyou Sharingan eyes first!

This would mean something had Madara received Ashura's chakra before awakening Sharingan
