Never Got to Say Goodbye: Came dangerously close to this after his row with Sousuke. Thankfully, Sousuke survived thanks to Shino's wish.
Older than They Look: Is suppose to be 18 but is cursed by Murasama to remain the same age as when he became his host.
Ping Pong Na´vetÚ: Though he's really [18 at times he truly acts like the age he appears to be. Even lampshaded at times by others. And at others he comes across as much wiser than his years and more in tune to what is going on.
Your Days Are Numbered: When he was ill as a child. It is also stated that if he were to remove Murasame from his body and become a normal boy, he would die in a few days due to the illness still intact in his body.
Major Injury Underreaction: Shakes off even severe injuries like they are nothing. He literally can't feel pain, which can and does become a problem if he suffers a life-threatening injury without realizing it.
The Team Normal: Or as close as one of the eight dogs could be to normal. Unlike the others Keno's familiar/companion doesn't grant him any mystical abilities that he uses in combat, or outside of combat for that matter. Kokonoe just gave him her heart.
Knight in Shining Armor: And played not in entirely positive light. He does nothing despite knowing Seiran's Cold-Blooded Torture to Genpachi, and it isn't until one of his insects gives Hamaji a papercut that Kaname finally takes action.
Plucky Comic Relief: When he is not pissed, he always ends as this thanks to Hamaji's attitude.
Ship Tease: With Hamaji, who does seem to like him back.
Nice Job Breaking It, Hero: Literally, and twice! The first time around it crashed on Shinonome's barrier, causing heavy downpour on the mountains before said guardian went berserk. The second time, it crashed on another barrier surrounding the Church, causing Lilith to come out and out for Shino's blood. In episode 22, Shino actually considers weaponising this to break the barrier in the tengu territory.
One-Winged Angel: Any time Shino is mortally wounded, Murasame is able to take over completely, becoming a colossal, nigh-unstoppable canine demon hell-bent on devouring enough blood to undo the damage Shino sustained, most often by eating someone whole outright. Only The Power of Friendship, courtesy of Sousuke, has been shown to be able to make him snap out of it.
Power at a Price: Its previous wielders have been said not to meet pleasant end with their lives.
Heroic BSOD: Played for Laughs. When she comes dangerously close to killing Shino and Sousuke just because they happen to step on her territory, Ayane appears and calls her "mean" while running away, causing her to briefly suffer this.
Blessed with Suck: He originally chose Nachi's brother, Yuuri, to be his master but the latter could not see him. When he went to the mansion of the Sacred Beasts that had a special barrier that allowed the unseeable spirits to be seen, Yuuri was distraught with what he saw and retreated into seclusion. Thus he had to retreat his choice and chose Nachi who is able to see him.
Technicolor Eyes: He actually did this on purpose, taking Kohaku's left eye because Shino thought they were pretty. He meant to collect her other eye as well, but Shino mercy killed her first.
Villainous Breakdown: He was more than happy to help Tamazusa... until she mortally wounded Shino and decided Shino's going to be the host for her dead child.
Bigger Bad: Or at least, would have been one if it weren't for the wrench that Shino unintentionally threw to Tamazusa-hime's plan.
Sealed Evil in a Can/Sealed Good in a Can: By default, it should have been the latter due to the fact that she was the one who sealed Tamazusa-hime away. She came dangerously close becoming the former when Tamazusa-hime attempted to use her soul, though.
Jerk with a Heart of Gold: Somewhat. She is quite a slave-driver even to Shino, but she genuinely cares for him and is shown to make quick friends with Ayane and Yana. The reason she wants to go to school is so she can become a doctor and find a cure for her adoptive brother.
Shorter Means Smarter: Among the orphans, she is the smallest one, and her intelligence is noted several times.
Age-Appropriate Angst: She's a fourteen year old girl who was from birth raised and treated as the living embodiment of one half of the local diety. She also was constantly made to grant others wishes without any heed to her own.
Genki Girl: Her new found freedom from her status as a "living deity" has given her quite a bit of energy and cheer.
Hikikomori: Since she was born, she has never left the shrine. Until she is freed from her "living deity" status.
I Just Want to Be Normal: Very much so; the main problem lies in that she refuses to voice or truly acknowledge said wish, which is why she and the village suffers so much. Once she does, she gets her wish.
