too lazy to read all post (i only read OP), but let me make this quick
if i was Ryoma, i will kill Elise, even she is cute, twin-tailed, loli, children, not-legal, because the reason above, i will shoot her like Takumi did also regarding war policy.... NONONO, this is GAME not REAL LIFE, if you still apply IRL rules to game, what are? 8 years old? ps: no, i dont hate nohrian except lago, garon, hans, and zola, but really, sees someone who compare IRL rules with game totally irk me, i know conquest story is good, and birthright story is cliche, but please stop using IRL rules, with game, everything can happened on game
