Also general question: is Sotenbori Arena really better to grind than Yokohama Underground?
The only time the underground dungeon is preferable is super late game since the first dungeon has that hobo that only takes 1 damage for each attack. You get 12k xp from him Iirc. Even then it's debatable whether that or the arena is faster overall.
For now stick with the arena since you want xp and rare materials. Just replay floors 15-25. For quick rare mats and xp.
Grinding money in this game is very annoying since those evolved weapons start getting super expensive at the ex +3 level. Real estate is the best non gambling way to make money and it is so slow.
