When it comes to travel-theme, the most popular isekai are those placing characters in virtual worlds of Massive Multiplayer Online Role Playing Games (MMORPG).

In Indonesia and other Asian countries like the Philippines, Thailand and Malaysia, Japanese anime are very much in demand as main forms of media entertainment not only for children but also for young adults. Apparently, even as the Millennials and Gen Zers have come of age, they still make up a large population of anime consumers in their respective country.
