Ah, My Hero Lady Tsunade! - S11.E237

Tenten remembers when she was little and how she really wanted to become like the legendary Tsunade. She finds out through hard training that she won't be capable of the strength Tsunade has. She also finds out that she won't be suitable to be a medical ninja for her poor chakra control. But at last, she discovers that she has the ability to summon ninja tools, thus creating her own style of fighting.
