Childhood anime series were almost all about orcs and talking animals.
The heroine, Mori Meiluo, is portrayed as a sickly princess, not pretentious, silly, and slightly sweet.
Traveling through a different world, I imagine it should be a Japanese-style magical world with orcs, elves, and dragons.
The male protagonist is undecided and may not have CP. The female protagonist's personality is different from that of people in this world and she may not be able to learn magic, but she will be a summoner.
Purpose: Reminiscing about childhood
