Heartwarming / Kamen Rider Decade

• The crossover episodes with Samurai Sentai Shinkenger have heartwarming moments for both the Shinkenger team and for Decade's group, the two biggest being when Natsumi welcomes Tsukasa home at the end of the second episode, and also another one from Shinken Red: "I don't know about the world, but we have no intention of driving you out."
  • One more:
    ShinkenRed: I don't think you're a destroyer.
    Decade: Based on what?
    ShinkenRed: Nothing.
• Arguably, the interactions between humans and Fangires in the World of Kiva arc. Most of the Fangires are in their human-looking forms but freely displaying stained glasses on their faces. You can see them in a group of friends with humans and some are even lovers.
  • Fittingly the first Fangire the heroes meet in this world is Ryo Itoya the spider Fangire, who seems to be decent if a bit eccentric guy rather then a psychopathic stalker. In fact he only reveals his true form because he thought it would be better in a photograph against the studio's Castle Doran backdrop. When, Tsukasa and Natsumi show hostility to him for not being human he runs away saying, once outside they see him making his way over to a pair of pre-schoolers, Tsukasa once again gets ready to transform but instead of attacking them, he's is venting his woe at what he just experienced at the kids, even crouched down to their eye level, leading to the kids chastising the duo for Fantastic Racism before they pat him on the head to cheer him up. It works. Words cannot sum up how adorable this is.
  • Yuusuke joined Wataru's guard after winding up in his world and tries to be a good friend for the young prince offering to give him a ride anywhere he wants at one point and even gives him a lollipop when he realises he hasn't eaten. The moments of him stroking Wataru's head like an older brother are particularly wholesome especially the last one where Wataru gets doesn't just tell him not to touch him.
  • He also speaks up in Tsukasa's defence even calling him a friend.
• During the opening, we see Tsukasa sitting on the ground with tears in his eyes, and an arm in a brown jacket hands him his camera. Then Daiki Kaito shows up. What is he wearing when he turns up in the opening? A brown jacket.
• Kamen Rider Ichigo summing up the legacy of the Riders.
  Dai-Shocker: What?! I thought you were all dead?!
  Kamen Rider Ichigo: So long as there is evil in the world, we will never disappear!
• Despite Wataru saying that Tsukasa role is fulfilled and thus he has no reason to exist and all the trouble that Tsukasa caused during his rampage as Violent Emotion, his friends and the AU Kamen Riders refused to give up on him and together they revive him with their memories showing just how much they care about him and trust him.
• The ending of the Decade saga: Tsukasa has connected and reconstructed all the worlds he destroyed, ensuring the safety of the multiverse. Having been brought back to life and his role complete, he can now go on an endless journey doing whatever he wants with his friends. The series ends with a new background on the studio wall unfolding into an endless road, and him sharing a final (actually well-developed!) picture with his friends.
• Despite their somewhat not-perfect relationship and events throughout the series sometimes make her question things, Natsumi refused to fully turn her back on Tsukasa and while at times he annoys her she truly comes to see him as a friend and maybe something even more. While others began to doubt him, she rarely turns her back on him.
