so.....i've been trying to perfect the abilities of a clan i have made up for my manga story and i want it to be as original as possible. my story started out as a naruto fanfiction but then i learned that it's just much better to have the story as my own rather than making it like a naruto fanfiction. why not create an awesome story right? RIGHT! so i did. i'm very proud of my story but i still need to tweak some areas in it. one of the things i'm worried about is the abilities i have for my clan.
a little something about the two clans:
the ikataki clan
a prestigious clan that has been known as one of the longest living clans around. their the top ranking of the hierarchy. many believe their longevity comes from special powers they have that allows them to appear younger, some even believe the special power gives them eternal life (but it doesn't).

the ikataki clan has the ability to sprout angel like wings, black in color.
the hikari clan
distant relatives of the ikataki clan. it is said the hikari clan members all descended from the ikataki clan and it's often questioned on who is the strongest among the two. because of this unsure belief, the hikari and ikataki clan have been known to fight for the title of 'most powerful', wanting to prove that each are stronger than the other.

despite this age old battle, the two clans manage to put their differences aside and live under the same household as one united family. likewise, both clans harbor the same abilities, only their wings are white in color.
alright, now here's what i'm trying to work on:
i want the two clans to have a special ability that is different and at the same time unique. at first i had in mind of...how should i say it?....i wanted (say for instance the ikataki clan) to have the ability to control the elements of darkness while the hikari clan control the elements of light. the question is, in what shape or form should they control it? with their hands, with their minds, with hand signs (again trying to not be like naruto), with special spells they can chant and then cast? all of these were some of my first guesses but now i'm not so sure. what's your opinion?
