(Gintama) Matsushita's Tale

"A long life, from now on, shared with you." A daily-life story about two old monsters dressed up in a rural romance, with the female lead's (adopted) daughter, children from the private school, friends from across the universe, the Heavenly Beings, the Tendo Institute, and others making appearances.
