### 第4章におけるエキドナとスバルの対比について
エキドナの提案する契約は、論理的には最も効率的で被害を最小限に抑える解法でした。しかしそれはスバルの魂をすり潰す前提のものです。スバルが彼女の手を取らなかったのは、効率よりも『誰の犠牲も納得しない愚かな意地』を選んだからに他なりません。

### Regarding the contrast between Echidna and Subaru in Arc 4
Echidna's proposed contract was logically the most efficient solution with the minimal statistical casualties. However, it was predicated on completely grinding down Subaru's soul. Subaru refusing her hand was solely because he chose 'foolish stubbornness that refuses to accept anyone's sacrifice' over cold efficiency.
