The first season of the anime consists of only twelve episodes and thereby comes to an end on June 26, 2019, or closer to this date. And we doubt that the announcement of renewal might appear on the official website of the anime this June or even this year. Unfortunately, this is how the world of anime works in fact. As a result, all we can do is to make a forecast based on the statistics and some assumptions based on solid ground.
Kenja no Mago has received generally favorable reviews from the target audience, and this fact, no doubt plays in favor of renewal. On MyAnimeList, Wise Man's Grandchild holds a score of 7.41/10 based on over 18,400 votes, and this figure looks above average.
Most likely, you know that Kenja no Mago is based on a Japanese light novel series of the same name, which currently contains nine volumes. A bad news is that the light novel apparently ended serialization back in December 29, 2018, when the last, ninth volume had been issued. It's not clear to date, whether a 12-episode television adaptation covers the entire amount of source material or only 3-5 volumes, since the first season of Wise Man's Grandchild is currently airing.
As a result, we have only two scenarios of how the subsequent events might develop. In the worst case scenario, the twelfth episode of the first season concludes the same way as the original light novel series. In such a case, we have no chance to see Kenja no Mago Season 2 someday. To be honest, we doubt that the Silver Link studio managed to adapt all the nine volumes into a single-cour anime.
Therefore, in the best case scenario, we could have enough source material for another television adaptation for at least another single-cour 12-episode season. Ideally, we see a three-season anime, each adapting three volumes of the original light novel series. Unfortunately, we will have the complete data on the subject only when the first season is concluded.
Another key factor capable of affecting the decision on renewal is the BD/DVD sales of the franchise. Yet we can't use such data right now since the sales would start after the Season 1 finale.
Summing up, many indicators are pointing out that Kenja no Mago may have a Season 2. However, we will have to wait to confirm or disprove our forecast. Nonetheless, we tend to believe that Wise Man's Grandchild will return for Season 2. We we right or wrong, it would become clear soon.
Kenja no Mago Summary
The story focuses on a Japanese salaryman, who died as a result of a car accident. He was reborn in another world, becoming a child. He soon has been picked up by Merlin Wolford, a patriot hero, who has given him the name Shin. It's worth mentioning that the world where Shin appeared is ruled by sorcery and magic. Shin thereby turned into a grandson of Merlin and has learned Merlin's teachings.
