Time to belatedly introduce the remainder of the game cast! This time we'll hit the characters from Kurenai.
Flandre Scarlet is the little sister of Remilia Scarlet, mistress of the Scarlet Mansion. Flandre (Flan for short) isn't technically allowed to go outside, on account of her extreme destructive power and childish playfulness- with said extreme destructive power. Her EX Spell powers up her attack, but she can only use it once a minute.
Ibuki Suika is an Oni who likes partying, drinking, and fighting. It's said she hasn't been sober in centuries. On account of debuting in the first fighting game, she's got quite the reputation as a tough little brawler. Her A-type (Suiki) has a Spell Card and Charged Spell Card which cannot be knocked down by any other attack (as near as I've been able to ascertain).
Reisen Udongein Inaba is a moon rabbit living in Eientei. She's a serious sort, and doesn't fool around much. Because of her attitude, she gets pranked a lot. Her EX Spell enforces Low Tension in the player it hits for ten seconds, crippling them.
Fujiwara no Mokou is a human born centuries ago in Japan who gained immortality from an elixir. Her theme is the phoenix, and accordingly she uses fire-based abilities, and resurrects after she dies. She's serious most of the time, especially with strangers, but she'll relax that with her friends. Her EX Spell leaves the target burning, taking damage over time.
Shameimaru Aya is a crow tengu who manages a newspaper. She can always be seen with her camera in hand. To sensationalize her paper, she's known as a paparazzi, taking embarrassing photos for publication. Her High Tension Spell hits all around her- it doesn't draw in other players like Utsuho, but its area of effect is bigger.
Kochiya Sanae is the Shrine Maiden at Moriya Shrine. She's a human originally from our time who got into Gensoukyou. She's a knockover for anime, games, and other pop culture. Her EX Spell heals her for a few seconds- but it also tells her opponents, "Smack me, now!"
Komeiji Koishi is another little sister, this time of Komeiji Satori, the mistress of Chireiden. Due to her powers, she is hard for layman to discern- she only registers to their subconscious minds. Spiritually powerful mediums and people frequently exposed to her can detect her normally. Despite her pool of acquaintances being badly limited, she's quite innocent and playful. Her High Tension Spell is another in which she rushes through a large hit area.
Hinanai Tenshi is a celestial living in a paradise atop a mountain. She isn't so keen on paradise, though, so she causes trouble in the world below when she gets bored. The fun, for her, isn't the trouble, but the people who come up the mountain to beat her up for it. Some even say she's a straight-up masochist. Her EX Spell gives her super armor for ten seconds, but she can only use it once a minute.
Tatara Kogasa is a monster umbrella (no, really!). She likes to go around surprising people, but isn't very good at it. In fact, she tends to get surprised more often than she surprises! Her EX Spell blocks anything thrown at it, for a second or so; supposedly it yields an offensive hit, but honestly, I've never seen it connect.
Houjuu Nue is a shape-shifter whose true form is unknown. She gets off on scaring people, and got sealed underground for her success. Since she was freed, her true form has been revealed, and her scariness went down as a result. Her EX Spell will hide her player data from other players, so they can't see her health, tension, spark gauge, team, or spirit gems (those last two don't change over the course of a match, but the EX Spell still hides them).
So that's Kurenai. Ten more characters, for a total of eighteen.
