I. Hate. Fishing.

Guild Quest Lv1.3 - 目指せ釣り名人 (Heading toward being a pro fisherman)
Main: Get 3 黄金魚 (ougongyo, big gold fish).
Sub A: Get 2 小金魚 (shoukingyo, small gold fish)

I'm not a biggest fan of the fishing. In area 10 there are a seemingly-infinite supply of worms (釣りミミズ) which you can use to catch the fish. Both appear in the same area so just fish as long as you can then go and put them in the red box (納品ボックス). Remember to put the Sub A/B items in FIRST as you can't get the cash for them if you put the main item in first.
