Bakumaru is drives by a strong sense of justice and heroism, having accepted his duty as an Eto Ranger. He can get pretty reckless, such as charging straight into battles that he can't win himself. He can also be egostical, sometimes believing he does all the work, but he still remains a nice person at heart.
Bakumaru originally had ailurophobia (fear of cats, which makes sense because he was a mouse). When he first encountered Genen (a cat), he literally fainted while standing. However, in Episode 21, Gao helped him get over his fear and Bakumaru was able to confront the enemy.
