Shioru Aia

Shirou is the youngest of his 4 android brothers. He is the most unstable out of the 4 of them thanks to his emotions. He has this defect where if he gets too angry he can self destruct himself and cause massive damage around him. He acts like a rebellious kid and hates humans. He will only listen to his brother and thinks of humans as weak and evil. He looks up to his brother and strives to be just like him minus the older's love and facination for humans.

Because his model is meant to represent a kid/young teen he must attened human school in order for the android brothers to stay in the human society. Otherwise the authorites will hunt him down and upon a background check they could dicover that the Aia brothers are not human and they could be deactivated&destroyed. Shirou despises using the humans cellular devices because he could just communicate with his brother using thier own connection that's more advanced than any other communication. But his brother Ichirou will not communicate unless Shirou uses the cellular devices. At school Shirou often takes a nap or walks out of the classroom because the lessons are so boring and way under his intellegence. This causes him to get in trouble with the school or at least it would if it wasnt for his perfect grades.

The A.H.I.W.A aka Automatic High Intellegence War Android, was designed by a japanese scientest whose goal was to make the most dangerous and perfect war machine. His idea was to give the machine human like features and intelegence to have it blend in with the enemy's society then destroy thier enemies with no notice at all quick and brutally. The first was AHIWA01 a model that heavily focused on mind of a human rather than the basic emotions and mannerisms. The second was AHIWA02 that focused more on durability than anything else therefore the model was almost brainless but still looked human. The third was AHIWA03 a model that focused heavily on the weapons. The fourth and last was AHIWA04 a model that had all of the sucess and advances in the previous models that heavily focused on emotion.

AHIWA0-1 obeyed and followed the orders of its creator with no issues until the other models were made and functioned. The model seemed to start a sort of bortherly bond with the other models and became more human as the days went on. AHIWA0-1 taught the other models that the are brothers and gave itself and them names. He was Ichirou (first born son), AHIWA0-2 was Jirou (second born son) AHIWA0-3 was Saburou (third born son) and AHIWA0-4 was Shirou (fourth born son). The creator (which they called father) only refered to then by thier models and treated them exsactly like machines. Their father had been ordered to destroy the models by his higher ups because of the danger and defective behaviors they harbored. Ichirou had watched in horror as his brothers Ichirou and Saburou were set on fire as the lab was bursting into flames. The seemingly brainless AHIWA0-2 shed tears as he ceased to function. Ichirou could only save Shioru from the fire. The two androids had no place to go and no purpose anymore. So they began to live in human soceity undercover.
