• Though V lacks a gender, the character is referred to as 'he', due to the more masculine nature of his character.
• Ri is present because V is posing as a college exchange student and Ri's family is hosting him.
• Though V wields guns very naturally, he is not necessarily a violent character. He uses violence only when commanded to, and the weapon-wielding maniac persona is only part of his job.
• The theme of dark vs. light appears recurringly in the story, for example in contrasting V's changing opinions on Meiji and Miasaki.
• Being synthetically made, V lacks a family name, but for unknown reasons repeatedly refers to himself as "Hiasashi".

More will be added as needed or if there are any questions...
