It is the headquarters of Njikoka Local Government Area Anambra State and lies approximately 20 kilometers from Onitsha along the old Enugu-Onitsha Trunk A Road that divides the town into two halves.
According to Late Chief Nwankwo Okakpu, a community leader and custodian of the peoples' culture, this man gave birth to nine children whose names are: Ogidi, Okpala, Chime, Okwui, Ene, Dejili, Akpuche, Ajilija, and Uru-Ochu.
Still in line with this historical origin, a spiritual mound was erected at the ancestral place where Agana-Diese lived and reared his children.
In keeping with the tradition, a day is set aside in November every year to celebrate "Uta-Anu" feast of meat, as memorial for the bond of relationship.
Our sources also had it that as time went on, "Okpala" who was then a prosperous farmer was in dire need of human assistance both for his farming activities and for physical protection of his vast and fast expanding territorial effluence.
It is also worthy of mention that due to difficulties encountered by the children of Dunu in sourcing wives from the neighbouring communities, Dunu solved this problem by establishing a spiritual dimension called "Iti Ofo na Ala" which made it possible for a section of his own children to intermarry among themselves, and this has continued till today.
According to further account of our sources, this Chime was a great warrior, adventurer, and statesman who came from "Ohafia" near Arochukwu in Abia State in search of slaves and merchandise.
It was indeed the Europeans, who found it difficult to pronounce "Mba-Agana" that changed the name to "Abagana" for easy pronunciation just like they did in other places like Nawfia, Nawgu, Onitsha, Awkuzu etc.
