Alexander is from Russia and makes western art while Akisame is from Japan and makes eastern art. Their differences are exemplified further by Alexander's Dou ki and Akisame's Sei ki.
He received strange vibes from Ogata and doesn't really trust him.
He's gotten along quite well with Diego after they spent some time in prison together.
He secretly respects Akisame for his art and fighting skills.
He's an obsessive neat freak and even follows his housekeeper around with a mop to clean after them when they are cleaning. He's gotten a bit calmer about that after taking in a disciple.
Matsuena thinks that he, Akisame and Hibiki Kugenin would make a great music ensemble.
He designs his own clothes (and always keeps them clean. He even carries antibacterial goods with him.)
