Bijudama is failed
Naruto(?) makes contact with 8b to ask how the cut/scar on raikage’s chest was made
8b replies that he doesnt remember it well but Raikage fell forward.
Naruto gets into the sage mode and prepares rasengan.
Getting as close (to Raikage) as possible he hits the previous Raikages arm with the rasengan.
Raikage falls down to hurt his own chest with his own right hand.
The last chapter said Raikages fight against 8b was his disgrace.
(The truth) was that
because he dug his own grave/blew himself away (he gave himself the decisive blow)
he couldnt tell that to anyone.
