Yeah, the good news is that Dragon Ball is written more or less for children, so all of their kanji has little hiragana symbols either above or next to it, so in the very least, I wouldn't have to actually learn kanji. I'm sure that at some point, I'd remember what the ones that show up often mean.
And I know what works for me, but don't know if it would work for you. I am learning hiragana at the same time as katakana. I find it to be a lot easier to just learn them together. So day one, I did "A," "E," "I," "U," and "N" and memorized both the hiragana and katakana for them. Then I did "O," "Ni," "Na," "Ku," and "Ro." Then I did "Sa," "Yo," "Shi," "Chi," "Ha," and "Ka."
Basically little by little, I'm doing like 5 at a time every week, though I learned these 16 in the matter of one week. Just keep repeating them so that I recognize them with ease. And I am doing hiragana and katakana together because I can use those to reference off each other. Like if I forget what "Ka" looks like in hiragana, I can think about what it looks like in katakana and it'll recall my memory. I find it a lot easier than having to relearn it later.
Dualingo is freaking amazing and I decided to learn the letters in hiragana and katakana before really attempting to build up on vocabulary. The way that Dualingo is structured is it uses hiragana so I felt that it would make it a lot easier if I already understood them by the time I went into Dualingo.
By the way, just for the fun of it, I picked up one of my Dragon Ball mangas and it gives me so much pleasure just recognizing the sounds. I only know a handful of words, but in my head I'm like, "Hell, if I can read it, I can just sound it out to Google Translate" lol Obviously I'm going to go and learn the vocabulary, but I gotta crawl before I can walk, so right now I'm learning hiragana and katakana to learn to "walk" with the vocabulary. It's awesome to recognize the characters in the manga and be able to sound them out. I wish I did this years ago, but c'est la vie.
