Before Natsuki Subaru ever stepped out of a convenience store and into the gritty, looping world of Lugnica, the isekai genre was a completely different landscape. While Re: Zero – Starting Life in Another World often credited with deconstructing the genre's power fantasies and introducing suffering as a central mechanic, it did not invent portal fantasy.
Isekai has only become associated with cheating schemes, harems and power fantasies in recent decades. Since way back, the theme is just a tool to explore different ideas, including romance, family drama and, of course, high fantasy adventure.

Digimon Adventure (1999)
Digimon Adventure, which quite recently got a reboot, is the original anime series of Digimon franchise. Many consider it as Pokémons rival, especially with the similar monster-raising theme.

In this world, they encounter curious creatures called Digimons. Digimons give them general information about the world.

Of course, their adventure is far from easy. After all, the digital world is filled with both glorious wonders and unknown evils.
Inuyasha (2000)
Takahashi Rumiko is a legend for a reason, and Inuyasha is her take on the time travel isekai. Even after decades, the anime still holds up very well.

The story follows Higurashi Kagome. On her 15th birthday, a centipede demon drags the hapless girl into the old well of her family shrine.

Fushigi Yugi
