Nikko

"A king who fears his power is destined to be overthrown by it. I am not afraid of my darkness, I'M GOING TO RULE IT!"—Nikko

Nikko is one of the protagonists of Heartbeat resonance. Nikko, like Hikari, is a part of an order of keyblade wielders ,called "Radiant hearts", which resides inside the world tree Yggdrasil. She is also a part of a group called "king trinity" which she formed with her friends, Hikari and Haretsu.

Appearance
Nikko is a slim, average height girl with dark blue hair, with three hair strands, one white and one yellow on the front and a white one on the back, at the length of a bit under her shoulders, Pale-light skin and silver eyes. Nikko's outfit consists a deep blue top with azure straps, silver decorations and a zipper running across the middle. She has an deep azure skirt which looks like it was diagonally torn. Her belt is brown leather with a golden crown shaped buckle and a few chains on the side. Nikko also wears shoulder plates, blue sneakers, dark silver knee-high socks, and a edged heart pendant that matched Hikari's pendant.

Personality
Nikko is usually a sweet, cheerful girl who constantly tries (and often succeeds) to lift up the mood of her friends. Nikko also shows many "girly" traits such as getting emotional during some romantic scenes and a weak spot for cute things.

Nikko has also shown to get angry quickly, especially when she catches her friends slacking of when they are supposed to be doing something, and often ends up comically beating the two (granting her the title "slavetrader" by Haretsu). Despite that she is usually calms down very quickly.

In combat, Nikko often shows a certain degree of pride, referring to herself as a "King" (even thou she is a girl) and looks down on her opponents, a trait she often claims to be a tactic to make enemies loose their cool. She can also be a little protective in battle and takes some pride in her teamwork with her friends.

Other traits include being teaseful and a bit flirtatious toward Hikari (often causing him to blush and become uncomfortable), her talent as a dancer, and occasionally, some romantic insecurity, like Hikari (a trait often used by Haretsu against the two)
