The sight of Mizuki whipping out with her acrobatics as well as her pipe on the crowd of thugs during the rescue of Iris from the fishery, and on Sejima's bodyguards when they're storming his estate near the end of Mizuki's route.
That said, something about her being only the second person we see Psyncing and somehow performing a Somnium Scan all by herself. note The latter is repeated again by someone who's not Aiba, but this is the first one we get to see And not to forget, the fact that she manages to succeed without any help from Aiba - not bad for the first time.
The Roaring Rampage of Rescue in Iris' Route. Moma shows up in a bulletproof ATV which Ota drives as support while Date and Moma fight off a horde of mercenaries in a virtual alleyway due to the setup of the warehouse district alongside Aiba calculating several dirty tricks against the mercs. Near the end, Mizuki is unleashed as their secret weapon as she manages to fight with only a pipe and avoiding being shot, leading to the rescue becoming a success. (For the time being...)
The climax of the Resolution Route, hot off from the soul-crushingly depressing Annihilation Route, which is exactly the brighter future the Date from that timeline wondered about and hoped to see.
Saito has retaken his body from Date while the latter got administered a sedative, leaving him helpless at gunpoint. Suddenly, Moma bursts in from above and nearly shoots Date, but quickly understands the situation and beats Saito away from Date. Moma reveals that Aiba messaged most of Date's friends to help him save Iris and Hitomi, which also becomes an epic heartwarming moment for the player since they've just experienced a timeline where Date was left with nearly no one, now they've come together to stop Saito once and for all.
Saito quickly shifts gears and threatens to kill Iris, only for Mizuki to pull an epic Dynamic Entry and unleashes a No-Holds-Barred Beatdown against the bastard while Ota rescues Iris.
Three months later... It's revealed that Iris is cured of her brain tumor thanks to Boss basically strongarming the MPD into footing the bill, otherwise they'll have a messy PR nightmare if the true story got out. Doubles as a heartwarming moment too.
