Heartwarming / Fate/Sunny Order

• The twins reuniting with their "Aunt Saber", Arturia, who is very happy to see them again. And then they summon EMIYA, who reciprocates Kana's hug when he's informed that she and Ritsuka are Shirou and Rin's kids. He takes to being a good dad/mom to them like a fish to water.
  • On another note, seeing that Shirou got married and had children gives EMIYA a newfound sense of hope that his past self won't walk the path of a Counter Guardian.
• Arturia and EMIYA having a moment in Chapter 6 when the latter gets splashed with water and ends up with Shirou-like hair.
• In Chapter 9 when Gilgamesh is summoned, EMIYA immediately runs into the Summoning Chambers with his weapons out to protect Ritsuka and Kana and is the only Servant to do so despite the bonds the other Servants have with the Tohsaka children. When Ritsuka and Gilgamesh prepare for a fight, EMIYA braces himself just in case he has to jump in. Despite claiming that he was not their real father when he was summoned, EMIYA has quickly gained a soft spot for the children.
• Both flashback interludes involve Rin and Shirou being good, supportive parents towards their kids.
• In a non-canon chapter, Shirou comes back from the dead briefly to give his kids lunch, tells Kana You Are Better Than You Think You Are (and that he'll see her at home), and tells Archer that, while he still doesn't like him, he trusts the counter guardian the most to keep his kids safe.
• In Orleans, Berserker!Lancelot recognizes Mashu as Galahad. When she defeats him, he smiles.
• Interlude 7 is basically "Ritsuka and Mashu finally make love". And it turns out the relationship is a threesome with D'Eon included, and the French spy loves his/her Master as well. Though it veers right into hilarious when D'Eon deliberately steals Mashu's clothes and Kana figures out that her brother finally got busy with Mashu.
