Takuma Hisa Sensei on their "From Aikijujutsu to Aikido" manuscript

Talking about the first time Takeda Sensei came to Osaka Asahi News office and presented himself as the Ueshiba Sensei Master.

"Ueshiba Sensei was always accompanied by three or four of his personal students whom he would use as his practice partners when he demonstrated. But Takeda Sensei didn't have a single student with him and always demonstrated his techniques using anyone who was brave enough to step forward.

He didn't have anyone with him that time either, so the strong students scrambled one after another to attack him. He sent them flying like he was twisting the wrists of babies, pinning them so thoroughly that they couldn't even cry out for mercy.

Everyone had been absorbed in Ueshiba's beautiful techniques, but right then we became completely fascinated by the strong techniques of this old master"

From the book, Daito-ryu Aikijujutsu, Conversations with Daitoryu Masters by Stanley Pranin (1996)
