Is the preorder DLC worth it?

[Life Pilgrim]

I bought the ultimate edition and then I realized I'm not getting the preorder DLC with it too which irks me. Is it worth it? 50% off atm.

Nope, completely pointless. I'm not sure what sub-quest is in question, but the rest:

Food item you get makes first 1-2 hours of game about 5% easier, and after that is completely irrelevant.
Bonyu is unlocked a bit earlier, but you don't have high enough level to beat her 3rd fight at that time, and by the time you get high enough level in Buu arc - you would've unlocked her training option anyway. Also her training doesn't really give any reward, so there's literally no point in accessing it earlier than post game.
