Synopsis
One man made an ominous prophecy while seeing the superiority of his army in the second Battle of El Mellow. The battle genius Jura. Jura was like a picture of an unmanned, irresponsible Ogishi, but there was only one person who couldn't stand up. The man-a half-brother, Rashid, believes in his brother's genius and struggles to protect the Rhodewake Frontier State in the Leerdam Evangelical Federation, which was defeated as Jura predicted. Sea animals with various special abilities, tactics, strategies, and new weapons color the birth of many unique heroes! Impressive warfare fantasy is here.
