Bah time to explain archer's entire story of his life using my knowledge

Spoiler

Ok Archer is Emiya shiro and he has regrets in his life after the stuff as explained in the wiki which he won the war and decides to follow his father's path as hero of justice. One year after the war Illya is dead and saber is gone from the end of the war(since archer's route is very much like Fate)
Shirou now determine to train his magi powers over used his training which starts to burn his body with over use of mana everyday ( hence the white hair and tan skin ) Which later he meets and asks Caren Ortensia who is Kirei's daughter who has been assigned to the chruch after kirei got killed by shirou. She helps Shirou by giving her a fire proof clothes and armor ( hence his red clothes and his black armor which protects him from the burns of over training overload) Then with this he grows stronger and continues his quest and with Rin as his companion he strives his goal but on one mission Rin gets injured and dies which gravely hurt shirou since he loved Rin(yea he got with Rin?) Then as he continues his goal he notices that inorder to save one another must suffer which one of the countless people he saved excuted him(scape goat) Yet he still continues his goal and made a pact with the world to be a counter gaurdian(weaker then a heroic spirit) which is a servant to save the world from grave danger. But by now he ideal prove to be failse since he has to kill some to save many(hence the gadgets of his UBW which shows his feelings as one that has become a machine) as the cycle goes on he soon becames bittered , despair , agony caused him to gamble on his only chance to be resummoned on the war in order to kill his youngerself and bring his time paradox to erase his existence all together yet in reality its not possible since countless shirou's from other timelines can become archer.
