Gozuki

ゴズキ

Gozuki leads the Empire's newly established assassination unit, the Elite Seven. He oversees the development of the group's members, refining their combat abilities and instructing them to become effective assassins. Eight years before the series begins, he collected approximately 100 children in Gifnora Forest, a region populated by Danger Beasts. Only the seven strongest survivors of this trial became his students. He addresses his trainees as his children, and they respond by calling him Father. He owns the Teigu "Murasame," which would eventually become Akame's.
He was extremely strict, bordering on cruelty, as demonstrated when he selected children for his purposes and separated Akame from her sister Kurome despite their protests. He stated that children must not rely on one another within his group. He also declared that he would not forgive them if they failed their missions.

Spoiler

Gozuki was a powerful and formidable fighter. He possessed the Teigu Murasame and wielded it with skill. Like other Rakshasa demons, he could manipulate his body in various ways, such as rapidly growing his nails and hair to pierce enemies or twisting his body to evade attacks.
