- ほかならぬ — the same ぬ form used PRENOMINALLY, modifying a following noun directly ("none other than N's") — ほかならぬ君の頼みだから断れない。
Notes
頼みだから断れない ("a request from you, of all people").

からこそ singles out a REASON clause as the one true cause, excluding rivals (難しいからこそやる価値がある); にほかならない does the same excluding-rivals work over a NOUN, naming what something truly IS or stems from (彼の成功は努力の結果にほかならない) — same rhetoric, a different grammatical target.
Lookalikes
Structurally identical N＋に…ない frames pointing opposite ways — にすぎない diminishes what it names, capping it at "merely" this and nothing more (推測にすぎない); にほかならない elevates what it names, asserting it IS precisely this cause or identity and nothing else — mistaking one polarity for the other flips the sentence's verdict entirely.
