Sometimes, an anime adaptation can make or break a manga or light novel series.
The former seems to be true for Naoki Yamakawa and Akinari Nao’s I’m Standing on a Million Lives (100-Man no Inochi no Ue ni Ore wa Tatteiru) manga.
Often times, an anime can make fans more interested in the source material, other times get turned off based on what they saw in an anime.
For starters, sales of the manga went up by 11 times since the anime first aired.
