Forza Esterna

 "We're not aligned with any faction. We are our own faction, our own family. So when you pick a fight with one of us, you start a war with all of us."

- Hakai explaining the purpose of Forza Esterna to Rias.

Forza Esterna is a group founded by Hakai Keiji that consists of various people from different origins. Many are noted to be highly powerful individuals and have the reputation of being the largest and strongest independent group in the Supernatural World. Despite having different charateristics and beliefs, the members of the group care for one another as a family and all are very loyal to Hakai. They are the main protagonists of Heir of Destruction.

Summary
The members of the Forza Esterna are from different races, backgrounds and nearly from every mythological faction with speical traits too. Many of them are hybrids while a few are humans and other species. Originally most were under Cain's care for the past few centuries but eventually Hakai gathered more comrades and officially formed the group to send a message to the other factions that they are an independent group that are not affiliated with anyone. Cain also mentions that there are even a few sub-groups, having been inspired by Hakai's actions though he usually takes care of that and the financial problems

Strength
According to Azazel, the strength of the group members is rather high. Many times the members have displayed skills on par with Ultimate-Class and Satan-Class combatants such as Devils and Gods. The leader, Hakai, is considered the strongest and eventually became listed as one of the "Top 10 Strongest Beings in the World".
