The bittersweet ending reinforces that Filgaia is saved but still a recovering wasteland. No one emerges unscathed, and the Valeria siblings' quiet, off-screen (or minimally shown) sacrifice highlights the hidden costs of peace.
Irving's arc ties beautifully into Ashley's (the reluctant hero who rejects singular destiny) and the broader lore of Lord Blazer/Anastasia. His willingness to become the villain in history's eyes to ensure survival makes him one of the most memorable supporting characters in the series.
If you'd like more on specific scenes (like conversations at Valeria Chateau), his relationship with Kanon or the party, comparisons to other characters' sacrifices (e.g., the Sword Magess), or how this plays out in the epilogue monologues, just say the word!
