SPACE ADVENTURE COBRA

Seeking reprieve from a painfully ordinary 9-to-5 existence, mild-mannered office worker Johnson visits the TM corporation, a company that sells virtual dreams. In Johnson's dream adventure, he's the notorious space pirate Cobra! Accompanied by his android partner Lady Armaroid, Cobra fights the lowlife scum of the Pirate Guild by day and saves sultry sirens of space by night. After the journey is over, events unfold that bring reality into focus. His experience wasn't a dream at all - it was a reawakening of his buried past! With the most feared weapon in the universe, the Psycho Gun, Cobra sets out into the galaxy in pursuit of love, fortune and fame. (Source: Discotek) — Description from AniList community (anilist.co).
