Keisuke Sanada (真田 卿介 Sanada Keisuke) is a sub character of fortissimo EXS//Akkord:nachsten Phase.


Keisuke is a tall man with short navy blue hair and navy blue eyes. As a bodyguard, he wears a black suit, which composes of a black vest, a white shirt with a red tie, black trousers and a pair of sunglasses.


Keisuke does not talk much, preferring to keep silent unless words are necessary; both his appearance and actions prove that he is a calm and cold individual. However, he cares deeply for Hinako Takamine like his own sister and will go to any extent to protect her, even if it means sacrificing himself. He also appears to be well-aware of Hinako's love for him, but does not feel that way toward her and cannot bring himself to.


Keisuke Sanada is the bodyguard of Hinako, the daughter of a renowned billionaire. He considers Hinako's well-being as the most important aspect in his life. As he was searching a way to lengthen Hinako's lifespan, which is being shortened by an incurable disease, he found himself invited to the magi sacrificing ritual of Ragnarök by Jin Arizuka, where he had the chance of saving Hinako's life. Although unwilling, he agreed to participate in the ritual, which was referred to as a survival game by the Game Master, as the Sleeping Demon (眠り鬼 nemuri oni), hunting down other participants to take their life force and use them to cure Hinako.

  • Mistilteinn (ミスティルテイン misutirutein): A set of 51 cards that Keisuke uses as his main offense. Keisuke himself acts as the core of the set; in other words, the defensive Joker, which regenerates both the cards and Keisuke's body when they are attacked.


  • Stormbringer (傷だらけの忠誠心 (ストームブレディンガー) sutōmuburedingā; English for Storm Bringer, Japanese for Wounded Loyalty): When any of Mistilteinn's 51 cards hit the enemy, Keisuke can activate their true ability: devouring the life force of their target.
  • Life Storm Raven (黒鴉なる生命の暴風(ライフストーム・レイヴン) raifu sutōmu reivun): Keisuke and Hinako's combo attack. Hinako gives some of her life force to Keisuke, which allows his cards to gain more power than before. All 51 cards form a wing-like shape around Keisuke in order to transfer some of Hinako's life force to his Joker card. The Joker then releases a beam of magical power towards its target. However, the cost of using such a dangerous rune renders the both of them unable to use their weapons.
