Motojirō Kajii

Motojirō Kajii is a member of Port Mafia. He is an explosives expert and has the ability Lemonade.

Appearance
Kajii has a tall, slim build and short brown hair with bangs cut at an equal length across his forehead. His eyes are covered by purple tinted goggles.

He dons a worn out, white lab coat with frayed sleeves and hem, underneath he wears a white button-down wrapped with a loose brown belt-like accessory. His coat has many pins, two on the left - one slightly larger yellow one with a face and a smaller black on with a red "X". On the right is an orange pin with an exclamation point, with metallic pins underneath.

He also wears worn out, frayed blue pants; a green scarf; and.

Personality
Kajii is as explosive as his lemon bombs. An eccentric, easily excitable man with an intense obsession over science and a lemon's shape. He has a habit of talking in an odd sort of "code" centered on the universe, referring to the Port Mafia's boss as the "Grand Marshal of Outer Space". Kajii seldom stops exclaiming his every word, and when he's not, he's mocking his adversaries or waxing lyrical of his intelligence.

For all his eccentricities, Kajii is an accomplished and seasoned science enthusiast. Kajii prides himself as a scholar of physics, applying science to every aspect of his life with multiple "experiments". He makes a point of questioning and doubting life at every turn and is especially intrigued by the concepts of life and death, including their relationships with higher powers, such as God.

To Kajii, there are countless fascinating phenomena that occur at one's death, hence he thinks very little of people's lives beyond being subjects for his "experiments". As such, he questions what death exactly is, and why it is so inevitable, as it is something neither science nor God can overcome.

Although boisterous and arrogant, Kajii proves a dedicated mafioso. As an infamous terrorist, he's one of the few Mafiosi publicly known, a fact he takes pride in. He views his "experiments" and murders as valuable progress in his never-ending studies and shows absolutely no remorse for the atrocities he commits. In a battle, he's brutal and sadistic, looking down on his opponents for both their weakness and "inferior" intelligence compared to his own. To top it off, Kajii specializes in surprise attacks and ambushes, showing incredible capability in placing bombs in strategic locations or rigging the environment to his advantage.

Of course, when on the losing end, Kajii wastes no time cowering in fear, as he isn't physically strong. This becomes especially apparent against Akiko Yosano after she "defies" an inevitable death. He can use this to his advantage, however, as when pretending to fear Margaret Mitchell and Nathaniel Hawthorne to lower their guard.

At the core of his person, Kajii views the world as tedious, and channels his frustrations into the lemon bombs he creates, calling the lemon, for its "ultimate geometry", the destroyer of a tedious world. He alludes to viewing the mafia as an escape from tedium, as it allows him endless opportunities to carry out his "experiments".
