Maybe a Fake Gintama

"Maybe a Fake Gintama" by Mr.Kee follows Kawaki, born from a planet's dragon vein (Altana). His journey begins with an encounter with the universe-traveling Umibozu and Umibozu's girlfriend, Kouka. By chance, Kawaki arrives on Earth and is profoundly influenced by his teacher, Yoshida Shouyou. He also forms friendships, notably with a distinctive trio: a silver-haired, curly-haired eccentric; a short man with purple hair; and a mischievous individual known for his catchphrase, "Not Zura, it's Katsura!" This is presented as a Gintama fan doujin, not a transmigration story. The narrative explores themes of cosmic wars, fanfiction, friendship, a handsome male lead, immortals, a male protagonist, sword wielding, wars, and a weak-to-strong character arc. For Gintama enthusiasts, this fanfic is suggested as a potential read, though opinions on its quality vary, with some expressing skepticism due to its fanfiction origin and author tag.
