や～！！新いＢＬＯＧＳＫＩＮは自分が作った名のね！どう？美しいと思いですね．．．大好きだよ！あの七の罪は七の大好きな男の子が変わった...　ハハハ．．．！！　
in fact, i just thought since i have 7 guys then might as well put them as 7 sins... oh well i guess if you look at them another way, each of them do have a 'sin' that they carry i guess... i shall explain a bit here...
jin (samurai champloo) - killed his master (not purposefully...) and was being pursued by other followers of the same dojo for doing so
haruka (tactics) - the sin of mass-killing when he was a then a ruthless goblin, hence ended up being sealed. subsequently released by kantarou, who wanted to befriend an ogre-eating goblin.
byakuya (bleach) - carried his wife's sin and atoning for it by subsequently taking care of rukia (and someone being super cold to her)
chrno (chrno crusade) - was a devil who killed relentlessly for 'freedom', then lost his demon's horns and was trapped in a child's form due to loss of power
abel (trinity blood) - a krusnik, vampire who feeds on other vampires (that's sinful enough eh...)
loki (matantei loki ragnarok) - an angel expelled from heaven because he was thought to cause ragnarok (end of the world) and consequently gets pursued by odin's assassins
squall (final fantasy 8) - denied the world of all relations and seen as a lonewolf, he was actually shrouded by his orphanage past... (play the game to find out!)

oh now i remember who i forgot to put... haji and edward... oh well that would make it 9sins.... (-_-`) 残念だ！
