Runaway - Aisuru Kimi no Tame ni

Both feature a group of guys who are on the run from a group of people and a young girl who is involved. In Wild Heroes it's an ex-gang protecting a girl from an organization whereas Runaway is a group of criminals who help a young girl while they were on the run from the police. Plus Tsukamoto Takashi is in both.

Both feature main characters on the run. Despite the fact there are several leads in Runaway, one portrayed by Ichihara Hayato also has a critically sick daughter (his primary reason for fleeing).
