History Heartwarming / BeyondTheBoundary

** Akihito and Mirai's TheyDo moment. The two of them are standing in a field of flowers (like the one shown in Mirai's scrapbook earlier in the film) just as the sun is rising. Akihito and Mirai both extend their arms, confess their love for each other and ask the other to stay with them forever. The scene mirrors the ending theme from the series, except this time both parties are reaching out and reciprocating. After all the crap these two have gone through, you really can't help but feel happy for them.

--> '''Mirai''': Senpai!\\

* Initially the Literature Club are only together because they are forced to be in order to [[spoiler: hold off the titular EldritchAbomination sleeping within Akihito]], not because they like each other. However, starting from The Fireworks at the Festival of Episode 5 they bond through the common ground of being loners and outsiders in a sea of humanity. They continue to bond and become friends during [[BreatherEpisode Episode 6]], and by the finale of ''I'll Be Here'', their friendship is as warm and true as one between a family.
* Episode 4, when Mirai [[spoiler: gives Akihito a CooldownHug to suppress his rampaging youmu side.]] It signals the point when she actually starts to see him as a friend [[spoiler: and not just her target]] and the ending scene shows Mirai has accepted him enough that she's willing to share her food with him.

* In episode 10, [[spoiler: Akihito's dream]] is equal parts this and TearJerker. There's Mirai apparently [[UnbrokenVigil never having once left his side]] when he was injured and continuing to take care of him as he's recovering. [[spoiler: Later that day, in the clubroom, Akihito finally decides to ask Mirai out on a date, but she turns him down, saying that he should've asked her out earlier. She reveals the day is AllJustADream and Akihito is still comatose in the hospital. The two are then taken to a field of sunflowers at sunset, where Mirai tries to give him one last kiss before saying goodbye.]]
* In Mirai's message, [[spoiler: she talks about how she knows now her powers are meant to save people, and she was not cursed, but blessed. She tells Akihito, now that he can die a normal death, to please live a normal life, like he once advised her to. She finishes by turning her CatchPhrase around, saying: "I don't feel unpleasant at all."]]

** Akihito agreeing to meet with Mirai at Aizeriya (the Mexican restaurant they first had dinner at in episode 1) after stubbornly trying to avoid her earlier on. The dinner actually goes pretty smoothly, and Akihito begins to realize that even though Mirai [[spoiler: [[LaserGuidedAmnesia has amnesia]], the real her is still somewhere deep inside and that he hasn't completely disappeared from her memories either.]]
** In the fight between [[spoiler: Hiroomi and Izumi, he manages to disarm her, then grabs her hands and tells her they should've shared in her darkness, to work through it together.]]
** [[spoiler: Akihito snapping Mirai out of her [[BrainwashedAndCrazy youmu parasite induced rampage]] by telling her he isn't alive because of his immortality, but because of Mirai and how she was stayed with him despite everything. He confesses to Mirai that he loves her, and promises that no matter what may happen from here on out, he'll always protect her.]]
