Determinator: Boundless energy and drive is his greatest strength. It's pointed out by his Madarou.
Hair-Trigger Temper: It doesn't take much to set him off. It's especially noticable next to the much more serene Tokine.
I Am Not Left-Handed: Inverted, "A lion boils even a rabbit with all its strength!" He goes all out, even on puny Ayakashi.
Idiot Hero: Somewhat. In most series he'd probably be considered a fairly smart fighter; he just stands out here because everyone else fights very intelligently and he tends to fight through instinct and pure power too often. His older brother and Tokine are the major foils.
I Let Gwen Stacy Die I Let Gen Die: He blames himself for being able to save Gen, and uses this as his motivation for revenge.
Likes Older Women: Yoshimori likes older girl Tokine. Later in the manga, he saves another girl of similar age from a high fall and she briefly becomes his Stalker with a Crush. This has led to others accusing him of preferring older girls. The previous name for this trope, Cake Eater, created a pun because he's also a cake otaku.
What the Hell, Hero?: Once from Tokine for intentionally getting captured by Kokuboro, forcing his allies to endanger themselves to rescue him, and from Tokiko, minus a slap, for trying to save the school from an Ayakashi swarm with a technique he had NO IDEA how to use and probably would have ended up killing everyone.
Tsundere: Mild version. Alternates between fanship fodder moments with Yoshimori, treating him as a coworker/classmate, treating him like a kid brother, treating him like an annoying kid brother, beating him up for annoying her, and beating him up while crying her eyes out for worrying him, then playing the trope as straight as possible by beating him up while trying to apologize to him.
Weak, but Skilled: She doesn't have Yoshimori's endless energy or sheer power but she has far greater accuracy and skill in manipulating Kekkai. The logical conclusion is that her signature style switches from giant Kekkai that she implodes around Ayakashi too small, to thin Kekkai that she uses to stab them and hold them in place.
Why Did It Have To Be Cockroaches: She's terrified of cockroaches. Probably not helped by the bug Ayakashi that scarred her hand as a child, but fear of cockroaches also runs in the family.
Badass He has Yoshimori's level of power combined with Tokine's maturity and skill.
Legendary Carp: His partner, Kurohime, is a giant black koi that swims through the air.
The Leader: of the Night Troops. He's either Type Charismatic or Mastermind; his troops seem to like him but he often acts as a heroic mastermind to counter the more villainous elements in the Shadow Organization.
Telepathy: Limited by several things. Kekkaishi and possibly some other ability users block it and even detect or interfere with it. It also provokes a red right hand in the form of his eyes flashing demonic when he uses it. This is worse than it sounds as he needs to be close for it to work. Lastly, Zen is afraid that he will be ostracized even by the other Yagyou if they find out he is able to read their minds, so he does his best to conceal his ability, even when he has information that he desperately would like to share.
How to best describe this sadistic Really 700 Years Old demon? For starters he lost his memory and is always trying to get it back, and at the same time wants some sweet revenge on that evil big brother of his. How does he want to go about this? KILL EVERYONE IN THE URAKAI. Together with his Numbered minions, he masterminds and manipulates events behind the scenes as The King, an aged man, and as his current container, a young boy.
Abel And Cain: You might think Yumeji/Tsukihisa is the Abel to his Cain at first. Turns out, in comparison, Tsukihisa is much, much worse than Nichinaga could ever be.
Alas, Poor Villain: When his real motivations and the circumstances were revealed, it was VERY difficult not to feel sorry for him.
Body Double: He has the old body for communicating with members, while his main body was a child
Dimension Lord: After Okuni's death, Nichinaga took possession of her seashell pendant, which she appeared to use as a focus for some of her techniques. He has been seen using the eye-shaped portals Okuni commonly used for viewing.
Grand Theft Me: Both Nichinaga and his brother are able to forcibly take over the bodies of others, transferring their own minds into a new body. They have survived this way for centuries, taking over other ability users in order to gain a second power. However, repeated use of this ability causes the memory of the user to gradually deteriorate.
Heel Realization: When his big brother possesses his favorite minion and sets wheels of plots in motion to make him essentially lose everything again, he remembers, its reveal bombed what happened, Nichinaga repents with death.
Hellish Pupils: With two irises in fact, that make him seriously unnerving.
Sugar and Ice: To Suigetsu. He loves her, a lot. He just really doesn't show it much until the end.
Taken for Granite: Though rarely seen doing so, Nichinaga could control earth while in the King's body, easily raising protective barriers out of the ground that are capable of regenerating rapidly if damage
The Council of Twelve'
Tropes Associated With The Council Of Twelve
Authority Equals Asskicking: You must have absolute mastery of supernatural powers in order to be a member, they also are the twelve heads above everyone in the organization, only the Sousui is above them
Finishing Move: Dragon Hole, uho draws a hole upon the ground and stands upon it creating a network of smaller holes extending from the main one. He can make fire any number of energy pillars from the holes. These energy pillars extend far up into the sky. The more spiritually powerful the land is the more powerful and limitless the dragon pulses he summons are
Taken for Granite: Juho uses earth-based magic which requires him to be in direct contact with the ground. To preform his spells he essentially align himself with the dragon pulses of the earth and manipulate that power
The 11th seat of the group
Informed Ability: He was a member of the top officials in the Shadow Organization, yet does nothing to show it before being killed off by Schihirou
The Hedonist: Okuni lived to discover the truth behind any mystery that caught her attention.
Dimension Lord: Okuni is able to manipulate dimensions like Kekkaishi, but she uses it in a different way. She is capable of opening eye-shaped portals, which are used for remote viewing, as well as focusing tremendous amount of power on a target
Living Weapon: Kurosame. Described as a curse-power ability, which manifests itself as a black threads which compose the blade, coming from the hilt of the sword. These black threads are incredibly strong and can cut through even the tough nigh-invulnerable exterior of the Kurokabuto Ayakashi. The threads can extend at will and entangle an opponent and slice through it with ease with precision through the use of bold strokes. He talks to the sword denoting that it maybe sentient
Fluffy Tamer: Nura is a master demon tamer. Her control over Oni is so complete that she can command an entire army of them simply by being in the same local vicinity. Just by being near her, oni naturally desire to serve her and no matter what happens, they will not betray her. The oni are simply happy to give over whatever power they have to offer.
Fountain of Youth: She can use her ayakkashi servants' powers to make her younger in order to enhance her abilities
Healing Factor: Drawing out the powers of her servants can allow her to do this.
Body Surf: Both Tsukihisa and the Sousui have survived for centuries by taking over the bodies of others. By inhabiting the bodies of powerful ability users, they effectively have access to two abilities at once. Tsukihisa's technique is more advanced than the Sousui's.
Grand Theft Me: On Zero, and he's been doing this to several bodies over the centuries
Green Thumb: He has an entire forest under his control, . He has control over the growth and movement of trees, bushes, plants and roots. He can accelerate the growth of branches and vines and manipulate them as though they were appendages to bind and ensnare opponents. He can even finely control moss creating replicas of his own shape. His control even extends to the poison plants can give off.
Affably Evil: She doesn't really exhibit much animosity—nowhere near as much as the other Kokubourou, that's for sure. Then we learn that she not only lived with a human man, but even fell in love with him, which is what prompted her study of humans.
A Form You Are Comfortable With: She once maintained her appearance as a human for the man she fell in love with, who was somewhat scared by the appearance of a walking flower in a kimono.
Berserk Button: A minor one, since Aihi is largely stoical, but it's unwise to discuss just whather relationship with the man from her past was.
Lack of Empathy: He routinely treats Hime, the only being for whom he probably ever felt anything, so coldly, that you would be forgiven for thinking he has some sinister plan for her, and will discard her the instant she's not needed for it anymore (as he treats his minions). Actually, Byaku sincerely wishes to heal Hime, it's just that he so out of touch with others' emotions, that not only his reaction to his wife's bout of depression - after he disfigured her in an attempt to extend her life by magic - was calmly helping her to kill herself. He also fails to see why anyone might object to it.
Meaningful Name: "White," appropriate for his hair color. It also points back to his old identity; the "shiro" in "Shironuma" also means "white."
Really 700 Years Old: Though he looks like a man in his early thirties, He's actually nine years older then his friend, Matsudo who is a peer of Yoshimori's grandpa.
Breaking Speech: Delivers an extremely harsh one to Shishio. Also has the inability of having a conversion that doesn't involve messing the other's head. Fails with Yoshimori because he's too dumb to understand what he's trying to trying to get him to do.
Captain Ersatz: Very obviously based on Shishio Makoto. It doubles as Fridge Brilliance, Shishio after his death tells his loyal henchmen Hoji, that he'll conquer hell, Since there's a long time between Rurouni Kenshin and Kekkaishi's timeline, it's possible that he did in fact do that, considering his strength, and was awarded the form of a high-ranked demon, (ignoring the anime version where he's a bug eyed freak who got scared of being caught), and began serving Kokubourou out of boredom. Since no one in his time was really an equal to him, he began to search for the one person who can truly give the "feeling" of having his life on the line, especially since he can beat most demons on a reflex.
Even Evil Has Standards: Believe it or not. He kills off two of his surviving subordinates when they take Tokine hostage, scolding them for their "lack of aesthetic".
The Heavy: A lot of Kaguro's actions made him more important to the plot than even the leader's goals. Hime's neutral true nature also shows him to be the driving force and personal antagonist to Yoshimori
