Episode 3

"Magic of Bonds" is the 3rd episode of the "Sekai Saikou no Ansatsusha, Isekai Kizoku ni Tensei Suru" Anime adaptation.

Short Summary
The teacher who taught Lugh the magic was a beautiful young girl named Dia. Dia, a little older than Lugh, treats him as his younger brother and sneaks into Lugh's bed every night to sleep with him. Lugh wasn't unpleasant because he had to teach him magic, but he gradually got closer to Dia.

Summary
In attempt to measure Lugh's magical potential, Dia gives him a Fahr stone, a special gemstone that can measure a person's magic capacity. Lugh's power is so vast, however, that the Fahr stone ends up exploding. This gives Lugh the idea of using Fahr Stones as makeshift grenades. Over the following weeks, Dia and Lugh become emotionally attached to each other. Lugh proves to be an exceptionally fast learner, not only learning how to synthesize metals, but also how to create weapons. He and Dia even learn how to create new spells together, and on their last night together, he gives her a titanium knife as thanks for being his teacher, while she gives him her personal Fahr Stone. As Dia departs, Lugh's father decides that it is time for Lugh to assassinate someone for the first time while explaining the methods of the House of Tuatha Dé. His victim is a woman guilty of multiple crimes who tries to plead innocence, but Lugh, knowing that the woman is lying, kills her painlessly.
