Crows Gaiden: Linda Linda

Overview

This is a story about Hayashida Megumi (known as Lindaman), from the manga Crows, set in his middle school years. Hayashida is an incredibly strong, ridiculously large and very taciturn 'yankee' type middle schooler. Yoshidome Keiichi, a much smaller, weaker, and very talkative classmate starts to hang out with him, and slowly they become friends. All the while, large groups of people keep coming to attack 'Lindaman', due to grudges they have against him or even simply because of his reputation as being very strong.
