Claude D'Aspermont

Claude D'Aspermont, codename Sai is one of the recurring supporting characters of the series. Sai was one of the five first rosters in Akatsuki Prototyp Nr. 1. He is a secret agent for MI6, and as both holder and informant for Xinhua Computers, as well as happens to be a Colonel-ranked World War II veteran due to his ill history with Akatsuki's former ally, Murakumo. Kati and her parents are his main associates.

Appearance
Sai has a longer hair and mostly wore black outer business suit, and both red necktie and sunglasses. True by his mythical evil eyes, his eye color and shapes can change into sharp demonic looking yellow.

His hair and inner business suit between the first two games changes from black and dark grey respectively, then progressively toned to blue on both. His shoes was brown in Akatsuki-related titles, until it tones to blue in En-Eins Perfektewelt.

Personality
Sai is very intelligent and a gentleman, as well as a very good businessman who can successfully carry out his job. Sai has a good sense of humor and a comedic side, especially when it comes to humiliating Murakumo. He also has a hard time babysitting Kati from hurting herself in dangerous situations. As a client to Kati's parents, he genuinely cared for her and also being referred as her uncle figure, particularly being called Mr. Long Legs, much to Sai’s annoyance.
