for the past 3 centuries IS units have only allowed pure hearted females to drive them but for young hajime Montoya that is not true. during his hugh school entrance exam. he accidentally touched an IS Unit. in doing so it scaned him and chose him manifesting as a bracelette on his left wrists. all the while teachers were watching. the IS he touched was the bakuru IS it hadnt moved for 2 centuries and it moved for hajime. The town people always thought of him as a joke when he was 10 he was kidnapped while on his way to watch hs older sister compete in a IS Unit tournament which she was winning. but when he go kidnapped the kidnappers injected him with a drug that would try and manifest the two sacred gears in his blood but the drug didn't take effect till after he turned 13 in an instant his hair turn a pure white and on each of his leges appeared the sacred gear of albion and draig the two Holy dragons. they were seintient spirit items that gave power to their hosts in various ways. when he was busy wishing them to disappear they hid once again but they continued to help him in various ways. but they were known to block all IS units touched by the host and prevent links for 3 years for that IS but the effect did not activate for hajime. when he was 15 he gained the ability of schmerman. effectively making him monstrous he almost always won fights and his enemies never stood a chance he soon received the nickname the grim reaper because no matter how many times you hit him he did not fall and when he did he got right back up. he was going to go to school to contain schmerman but instead got and IS unit and immediately put under government protection and put into the IS Academy
