even after reading the comic you're still calling it romanji? I think you entirely missed the point it's trying to make.
You don't have to go as far as writing "roumaji" every time, but at least call it "romaji" for fucks sake. Why are you adding a N in there?
and you shouldn't be thinking in terms of romaji at all while you're learning unless you want to cripple your reading speed later on, there's no point in adding an extra translation layer in there (kana -> romaji -> pronunciation) just cut out the middle man and start treating them like their own characters with their own sounds independent of our alphabet.>but Romanji -> Hiragana I fail at
You're spending too much time dwelling on beginner material. We don't necessarily insult people for taking too long to do things here because they are dumb, it's because you're wasting your time.
If you keep trying to be perfect at something before you move on then learning japanese is going to take you 20 years. When you move on to more advanced things you are still seeing the basic stuff every day but in different ways and you learn it faster without realizing it. You learn faster when you push yourself to more advanced material
TL:DR move on already, start learning grammar and/or vocabulary, and avoid any sources that use romaji (tae kim is recommended for grammar guide). In a few days you'll get better at kana than you probably have in the last month
