Berserk Button: A guy under Chaos' influence stabbed his foster parents. Guess what happens next.
Beware the Nice Ones: In the anime he's soft-spoken, displays some Cloud Cuckoo Lander traits on occassion, and is extremely forgiving... but when he puts his mind to it he'll pummel you into the ground. Nicely.
A list of all the playable supporting characters in the game. Please note that some of these characters such as Hisui Kisaragi play a bigger role in the anime and most were omitted from the anime altogether. Also some had vastly different personalities but as the game came first this character list will be organised according to the character listings from the game to make it easier to read for characters that were omitted.
Ascended Extra: In the game Kisaragi was not all that important to the storyline, but his role was greatly expanded upon for the anime.
The Mole: In the game she is actually working for her brother. In the anime, Tendou used her to reel Tatsuma into his trap.
Redemption Equals DeathShe never really wanted to go through with her brother's (game)/Tendou's (anime) plans and was very fond of Tatsuma but she dies along with her brother when the building burns to the ground (game)/turns into dust (anime).
Redemption Equals Life: If you meet the requirements Sayo can come back from the dead and join you virtually at the end of the game.
Together in Death: Sayo stays behind in a burning building to die with her brother Shirou.
Ravens and Crows (In the anime he turns into a Crow demon. In the game however he controls them. Karasu - said like 'crow', but is written with different kanji. He views crows as higher beings than humans, creatures who used to serve the gods but later fell out of favour)
Bullying a Dragon (Bullied all his life, has no friends, and then he gets special powers. Guess what he does with them.)
Dream Land (Of the specific person variety - in this case Reiji himself)
Heel-Face Turn: Eventually becomes a good guy and practises onmyoudo at Sakuragaoka Hospital.
Stalker with a Crush (In the game he becomes obssessed with Aoi after she is nice to him and he pulls her into his dream world)
Brother-Sister Incest (Again to Sayo. 'Your body and your soul... they belong to me. Your hair... your hands... your lips...')
Names to Run Away From Really Fast (Shirou has the character for 'death' in his name. If you didn't get the hint that meant he was an evil zombie-making doctor on a revenge spree, then you can only blame yourself.)
Together in Death (Sayo stays behind in a burning building to die with her brother, Shirou)
