“Ryohei Sasagawa (笹川 了平, Sasagawa Ryōhei)” quotes from Reborn!

Awesome! That's proof of his strength!

You dodged my extreme right straight! I'm really impressed with you now! Join our club, Sawada!

Tsuna and his friends are so passionate! Let me in, too!

It is time to let the one called Namimori's Rumble Fish teach!!!

Alright! My ULTIMATE power is emerging!

Real men only go straight! (when failing to make his bike turn corners)

EXTREME! (Catch phase)

(To Lambo) Smile... I said smile! Smile! Damn you!

This box is extremely yellow!

The dolphin has guts. I want him in my club!!!

(To Lambo) Don't you want to see Tsuna's mama again?!
