Okay, so Oretachi ni Tsubasa wa Nai doesn't seem like it would contain much in the way of learning material. It's got a modern-day setting and all that jazz. But it's turning out to demand very careful and involved reading. The scenario writer has something of a cult following for his distinct style, which basically means that his work is very clever but also harder to follow than the norm. I could probably spend the rest of the year just introducing stuff from this game....
1) 畷 【なわて】road between farming fields or rice paddies
2) 侵寇 【しんこう】a brutal invasion; to invade and pillage
I love this one. It combines a kanji used in common compounds meaning to invade, violate or trespass (侵害, 侵食, 侵入, 侵略, 侵攻, etc.) with a more unusual kanji meaning "foe" or "object of revenge" (寇 【あだ】).
3) 勝ち鬨 【かちどき】 (n) shout or cry of victory
4) 朝餉 【あさげ】 (n) breakfast | 昼餉 【ひるげ】 (n) (1) lunch | 夕餉 【ゆうげ】 (n) dinner
These are entirely new to me, haha. You almost always see 朝食 or 朝飯 (and their lunch/dinner variants) instead.
5) 躁病 【そうびょう】mania (as in the mental disorder)
