Full Metal Panic! Volume 8 by Shouji Gatou

Sousuke has been torn away, not just from Kaname, but from the entire life he’s made for himself. His flight brings him to a lawless border town in Southeast Asia, whose economy revolves around mech battles played out for sport and profit. On a lead that Amalgam is involved with the corrupt authorities there, Sousuke joins a ragtag team headed by an impetuous young local and her reluctant foreign sponsor. But as he seeks what he’s lost, will Sousuke lose what he’s gained?
