Day 5 
I read 3 pages of 僕らの天使ゲーム just to read something, and learned the word 抜群 ばつぐん (outstanding; excellent). I’m at page 110/354 so I don’t know how the story will end but I’m surprised it talks about a heavy topic despite being a book meant for primary school students (though it’s a good thing!).
Day 6
I read the first volume of ばらかもん 
I started reading it in my native language years ago and I had forgotten how young Handa looks in the first volume haha.
New words
飛行機雲 ひこうきぐも vapor trail (vapour) - when I read the kanjis I thought they were talking about a cloud that looked like a plane
平凡 へいぼん ordinary; common; mediocre; unremarkable - poor Handa 
肥える こえる to be discerning (eye)
荒んだ心 すさんだこころ dissolute mind; hardened heart
没頭 ぼっとう immersing oneself in
雅号 がごう alias
忠実 ちゅうじつ faithful
醜態 しゅうたい disgraceful behavior
倦怠感 けんたいかん physical weariness - I actually learned this word last week but I don’t remember in which situation 
瀕死 ひんし (on the) verge of death
自炊 じすい cooking for oneself
傑作 けっさく masterpiece
Interesting setting 
It really seems like a nice game, I added it to my wishlist!
