Since I've actually gone beyond one or two lessons, I thought I should keep things organized. XD
Note to first-time visitors: I haven't included a hiragana/katakana guide, even though I actually wrote one. So, you'll only be able to follow these lessons if you've already learnt hiragana and katakana. Kanji isn't necessary, though.
Lesson 1: The は particle Lesson 2: The の particle Lesson 3: Demonstrative pronouns Lesson 4: Negation and past of です/だ Lesson 5: Adjectives Lesson 6: Verbs (plain form and ます form)
