The first is Y/N's blade Jihi (mercy) she uses the blade on opponents that she spars with who she deems to have enough for her 'mercy' which being to not punish them by their decision. She was inspired to make this for a rumour from a Christian family member in her family how god would punish those that had carelessly used their life for sinful things (lgbtq is not sinning to her so don't worry my fellow LGBTQ's! ^^) and how he blesses people with good life's for the better those who uses their life to their fullest.Once nearing the end she would use a future move to show them mercy
After the spar match she would bless them for the better.. if they don't back down and are cruel she will embed the blade with haki until it's fully black and finish the opponent off barely alive or if she must without a heart beating.
!!Spoilers!!
Next we have Jikkō suru (execute) Y/N if in one of her points to just going full out will pull out Jikkō suru. Jikkō suru is a cursed blade she gets while in the world of one piece.. the blade looks red because it's stained by almost a country or two full of its past users blood who failed to be deemed worthy.. some are lucky to be alive with three of their limbs or two still in tact. Y/N when at her strongest point will use a move similar to Zoro and mihawk but far more dangerous from her mental state.. her mental state will become more fractured each time she looses her sanity during a battle filled with adrenaline and excitement as she calls it in the future.. the blade's gem is rumoured to be one from the pits of the earth and from hell itself and is why the blade is cursed.. it contains not one but two demons in the gem embedded in the blade.
