4

Kennosuke dines with the Shirahane children and Uncle Osho Yakushi, tasting modern Japanese food for the first time. The Ministry of Defense reports that six enemy giant mecha landed, with Japan defeating only one, while the units seem to be searching rather than attacking. At the Shirahane home, Kennosuke sees a TV broadcast of the Battle of Okehazama, triggering memories of failing to save his princess. Yukina takes him to a shopping mall, introducing him to the new world. They meet reporters who recall Yukina’s father, Takehito, theorizing about demons and aliens before he disappeared. Yukina shares her father’s notebook, which details the Washiba Clan’s destruction by an unknown power. A photo inside reveals a dark figure Kennosuke recognizes as the demon that attacked him and the princess 450 years ago. The epilogue notes that 3.7m tall MM3A single-seater defense units are called Dwarfs.
