"Is it light?"
hints are not helping at all when they give kanji and choices are in hiragana...
Yup, but they want weight here... the lack of context here is quite fun to deal with!
None of the kanji shown when I tapped on 'light' were even the correct answer!
"Naruto" had two characters named Omoi and Karui. Karui was completely carefree, while Omoi was always mulling over things and slowed down by his worries. Those two make it really easy to remember these words.
Dont show translations only in Kanji! Especially those we haven't learnt yet!
Kanjis are helpful to express the meaning faster and make the sentence more easy to read. If you don't know that kanji just go by the audio pronounce.
