Some minor changes, if somebody wants to comment before I edit:

Spoiler:

106 親しき人への想い / Thoughts to a Friend -> Feelings to/towards a Friend
Might be a personal appreciation but 想い/omoi (thought, feeling) seems more emotional than 思い/omoi (thought, feeling), hence feelings.

109 敵との対峙 / Confronting an Enemy -> Confrontation with the Enemy
Less indirect.

116 顔つき / Face -> Looks?
Might be confusing since I believe it's more like the expression a face does, but I can't think of many synonyms.

217 別れ、そして... / Parting, and... -> Parting, And...

414 機神界フィールド / Field of the Machine-God World -> ?
Wouldn't 'Mechanical God' sound more natural? (see below)

421,420 巨神胎内 / Inside the Giant -> Inside the Giant God
Added 'God' to keep the reference (機神-Mechanical/Machine God and 巨神-Giant God are key concepts in the game)
