Let me introduce sakumo to you kooko...
And he is committed suicide...... And he is repected person.....
look at jiraya , he didn't master rasenghan perfectly but he's the one who taught it to minato.
same goes for tsunade, she didn't master ftg but she's the one who taught it to minato since she is the last senju
And for this i GIVE to you chapter that you must reread again

And i hope you will know the true who is develop rasengan
hanzo was more powerful than 3 saninn but he lost to mere samurai .
i bet tsunade ( 5th hokage) can solo both hanzo and sakumo at same time
Did you know how tsunade got title sannin???
You need to reread when jiraiya meey nagato, yahiko and konan.....
Tsunade, orochimaru n jiraya lost to hanzo......
So your writing is don't have manga proof dude....
And you don't have manga PROOF that tsunade teach minato ftg.......
