Personality
While initially showing himself as an ordinary, clumsy and worried old man, he later shows more about his true character, keeping calm even when the other people trapped in Anne's room ran away, staying together with Atsushi and Tanizaki, and still maintaining his composure when the later was captured.

Mori, later reveals that not only is he good with strategies and planning, but also a cruel and merciless person capable of infusing fear on his enemies.

He is also shown to be quite the gentleman, being extremely polite to not only his allies, but to his enemies as well.

Despite being ruthless, he has shown a kind side to him: Mori is a good parent figure to Elise, taking good care of her and being extremely patient to her whimsical and mischievous nature; he also agreed to spare Kyouka for Ozaki's sake. And his subordinates keep him on high regard.

He also possesses and incredibly strong murderous intent which froze Lucy and even Anne due to their fear of him.

It is stated by Osamu Dazai that he is the 'Embodiment of Logic itself', considering how he keeps calm in any situation and being bound to exploit any apparent meaningless thing in order to beat his enemies.
