Archibald Laurence Kristin Kitagawa (18 May 2019) is a Lucian officer currently serving in the Lucis Army as part of Task Force 141 as part of Detachment K. Archibald is the first son of Naoto Kitagawa and Akiko Sugiyama. His name was given by his great-grandmother, Tsukuyo Kushineda. He is named after 2 EWII generals, namely his great-grandfather, Field Marshal Archibald Sugiyama and Erebonian General Karl L.K. Arseid.
Archibald is the first of Kiriya and Caroline's grandchildren. While it was not expected that Naoto would be the first of his siblings to have children, Kiriya and Caroline would grant their blessing to Naoto. He is nicknamed "Archie" by Kushineda and doted on him as he was young. He is very affable yet quiet and often an introvert. He prefers reading books and often loves to keep the company of his great-grandmother. He is the elder brother of Charlotte Kitagawa, who is his complete opposite.
