I will only give only three familiar power to mc because giving him all twelve familiar power is waste in twilight world, but if I made chin travels to different world then I will give him full power of koujo.
5th Familiar: Regulus Aurum - This familiar is capable of producing and manipulating electromagnetic energy. Kojou can manipulate the beam to create a force field around him. The ray is strong enough to destroy a barrier of divine oscillation and neutralize Wiseman's Blood energy beam, which was already capable of atomic-level destruction.
6th Familiar: Minelauva Iris - This familiar is capable of manipulating the laws of nature and also carries the cause and effect cutting ability.
10th Familiar: Dabih Crystallus - This familiar's ability is mental and spiritual manipulation.
MC will have these 3 familiar power and in exchange for other 9 familiar I will give him immesereable strength, true martial art mastery
