The term RIT means Rookie In Training, and was first used in Age of Empires II online ID back in early 2000s. RIT was originally a clan name on AoE2.
RIT_ninja's contributions are mostly made in the Initial D and Wangan Midnight communities.
Early contributions include starting Wangan Scans, a scanlation team, as well as translating Wangan Midnight Manhua into English text.
RIT_ninja later left Wangan Scans due to conflict of interest and began collecting Wangan Midnight Maximum Tune soundtracks that are hard to find as well as providing high quality rips of the original Wangan Midnight Maximum Tune 1 & 2 OST for remix purposes.
