ah i totally failed to get that horizon thing going, but if you want we can do a horizon thing via event? louis is hesitant in fighting/would prefer not to, but he has the tools for it and he would be able to tap into mimicking all the other powers he's seen from the vampires he's met in his life. it would challenge him to force to bend the horizon limits more since he has been playing it safe trying to be a normie (i know this weirdo). he could always pop into alucard's horizon at the worst possible time which is when a beast it attacking and be forced to fight. i am open to any of the beasts you listed. or if you want, i can offer louis' domain too. he would be forced to fight anyways so it won't get ruined. p open to anything!
