well duh. Riki's like 40, iirc, and Tora's around 17ish

and despite this, he, his father, and his grandfather managed to develop AI that passed the Turing Test with flying colors, AND is fluent in over 6 million forms of kicking ass.

I mean, said robot GF is one of the most advanced pieces of technology in Alrest that he built all by himself in a run-down shack, which he was forced to after losing his grandfather, father, home, and original robot GF design to a group of thieves, not to mention his introduction has him saving Rex and Prya from capture.

They're both silly characters who have a bit more depth to them once you start to learn more about their personal life and history. If's there's any Nopon who should be getting this treatment it's Tatsu, not Tora.
