Fusian have released this as "The Young Avengers", but "Avengeress" seems much more likely (even if it's not exactly a common word). Added it as an alias anyway though.

added prod. co., prod., prod. man., 1 writer, phot., ed., art dir. and sound.

I will soon delete the person 活寶 (only this credit), because I found out that it is an Alias of Ai Chi-San (added this alias today), who was already identified and added to Young Avengeress by one of our editors.

Thanks to the newly found Taiwanese newspaper archive (see dongdado thread), I found this Alias in a newspaper ad of Golden Sword (1969) in which Ai Chi-San played the main role.
