akira's sword design is inspired from my percy jackson days (so late elementary/middle school lol)! the gold-ish color on the outer part of the blade is reminiscent to celestial bronze, as she was gifted the blade to kill monsters and beasts. the name, ichor, is also a reference to the color! coincidentally these details worked out when I used her in p3 scenarios since the main mythology for that game is greco-roman .
