The extensive experience with combat burnt into my body
ended up with that grand name, «Aincrad style», but I couldn’t
help but to feel a mysterious happiness and profound
satisfaction when Eugeo absorbed it like water on sand. The
«swordsmanship» that formed the foundations of my ego for a
long time, despite me thinking it really wasn’t anything more
than a technique for games, seemed truly tangible for the first
time only after it was refined and blossomed within Eugeo—I
could even claim to feel that way.
