Dokonjō Gaeru (ど根性ガエル) is a manga and anime series created by Yasumi Yoshizawa.

Summary
While frog Pyonkichi is hopping in an empty lot in Nerima, Tokyo's Shakujii Park, middle schooler Hiroshi trips over a rock and squashes him. However, Pyonkichi is reborn as an imprint on the front of Hiroshi's shirt and now gives him advice and commentary on his life.

Characters

 * Pyonkichi (ピョン吉): . A frog who is crushed by Hiroshi, but his spirit lives on as a talking frog on his shirt, becoming a Flat Surface Frog (平面ガエル). Because said shirt is Hiroshi's only good shirt, he is always forced to travel around and interact with Hiroshi. They are equally obstinate and gluttonous and are always arguing like siblings. He is capable of jumping around and forcing Hiroshi to come along with him.


 * Hiroshi (ひろし): . The middle schooler who fell on Pyonkichi. He is quite gutsy and won't back down against Goriraimo, but is deathly afraid of Kaa-chan. His trademark is the sunglasses he wears on his head. Though his school has a uniform policy, he is for some reason allowed to wear his regular shirt.


 * Kyoko Yoshizawa (吉沢 京子):, New: Atsushi Tomii→Kaoru Kurosu, CM: Chinami Nishimura. Hiroshi's girlfriend. She is the daughter of a rather wealthy family, yet is a strong minded girl who will stand up for herself and participate in pranks. She initially pretends to dislike Hiroshi but becomes friends with him after he meets Pyonkichi, whom she believes is a cute shirt design.
