What Happened in That Time I Got Reincarnated as a Slime Season 3, Episode 16?
Hakuro Meets His Daughter for the First Time
Episode #16 ofThat Time I Got Reincarnated as a Slimebegan with a flashback, showing Benimaru’s first contact with the Tengu, which didn’t go particularly smoothly, as the representative they spoke to, Momiji, mistook the presence of one of the Beastketeers, Albis, as a veiled threat towards seizing their lands. After helping things de-escalate, Benimaru was able to speak to the Tengu leader, Kaede, briefly, and learned that she was willing to entertain their idea of building a tunnel through Tengu land, so long as Benimaru himself would marry Momiji. In shock, Benimaru said that he needed time to weigh this decision, and returned to Tempest.
In the present day, the Tengu delegation arrives for their audience with Rimuru, led by Momiji. Momiji is distrustful of Rimuru, even as he insists he has no intention of taking their territory, but they soon figure out that it’s due to past conflict with the former demon lord Frey that they are so suspicious. Once it’s made clear that Rimuru has no intention of allowing Frey to harm the Tengu, Momiji is able to relax a bit and open up for friendlier relations. That’s about the time when Hakuro returns from Falmuth, and Momiji lays eyes on her father for the first time. Hakuro is equally surprised to find he has a daughter, but embraces the role gladly.
