Iku only has one goal, take revenge for their brothers' deathsAfter years of training their aura, Iku heads back home to kill the man that killed their brothers. On their way, they cross paths with two young boys, Ren and Kei. Iku should be more worried about getting home but they can't help but see the similarities between these boys and their little brothers. Could these boys be a second chance? Could Iku protect these boys the way they couldn't do with their brothers?Iku's single thought has been revenge for the past eight years but leaving these boys to fend for themselves feels too much like the way Iku and their brothers were left to deal with their own problems. They have no obligation to these kids but neither did anyone to Iku and their brothers. They can train the boys and then move on. They'll give the boys the skills they need to take care of themselves and then they'll get back on their own path. It's more than anyone did for them. It'll be that quick, as long as they stop looking at Ren and Kei like they are their own brothers.Iku may not be ready to forgive themself but Ren and Kei might be enough to remind them there is more for them to live for.Redemption or Revenge.
