Luigi's Japanese Log - Day 2

Here I am again.

Second day, a new series. The so called S series -- with the following characters:

さ SA
し SHI
す SU
せ SE
そ SO

There is no SI sound in Japanese. The character し sounds like SHI.

The Human Japanese app presented what I call the "Z series" straight after. You have to add the ten-ten to get the following sounds:

ざ ZA
じ JI
ず ZU
ぜ ZE
ぞ ZO

I continue to memorize the previous characters with Anki. Everything is going smoothly.
