A new kind of momcom role-playing adventure! Thanks to the efforts of Masato and his party, MMMMMORPG (working title) has begun its transition to an official launch. In this triumphant moment, however, the Oosuki family’s final trials still await. Will Masato be able to defeat his father, the Demon Lord, by himself? Or will Mamako once again have to lend a hand? More importantly-can Masato safely say that going on adventures with his mom has brought the two of them closer…?
