Shinobi 7: Spring Ninja Festival! (春のニンジャ祭り！ Haru no Ninja Matsuri!) is the seventh episode of Shuriken Sentai Ninninger. This episode features guest appearances from Yousuke Shiina (HurricaneRed) from Ninpu Sentai Hurricaneger and Sasuke (NinjaRed) from Ninja Sentai Kakuranger.
After the defeat the team suffered against Raizo Gabi, Tsumuji has brought two new ninja teachers: the Kakurangers' Sasuke/NinjaRed and the Hurricanegers' Yousuke Shiina/HurricaneRed. After seeing the Ninningers in action, the teachers sternly declare that the team lacks strength and that Takaharu is not even up to par.
The Ninningers train themselves to get stronger in order to surpass Raizo in their next encounter. Fuuka tries to express her gratitude to Takaharu for saving her earlier, but to no avail due to her in-confidence. Tsumuji ends their training and presents to them two new teacher; Yousuke Shiina (HurricaneRed) of the Hurricanegers and Sasuke (NinjaRed) of the Kakurangers.
The two Sentai Red veterans demonstrate their proficiencies in their respective techniques and teach the Ninningers to master it. AoNinger even tries an air technique until HurricaneRed scolds him for the use of magic spells. While Raizo is nursed back to health, Kyuemon remembers Yoshitaka's claims that he knows nothing of the Shuriken of the End. The Ninningers receive their report cards with Takaharu being the lowest, but still willingly awaits for harder tasks. Elsewhere, a new Youkai named Nekomata is born from an abandoned watch.
The Ninningers and Sentai Reds are alarmed by his presence, but Takaharu is tied up and forced to stay at the dojo by his teachers. Kyuemon approaches Nekomata and asks him to fulfill a task, which he accepts. The Ninningers and their teachers arrive, but are overpowered by Kyuemon. With Nekomata goes into the past, Takaharu races into the time door. Sasuke and Yousuke watch in regret as they reveal what will happen to Takaharu: Nekomata leapt into the year 2005 to attack any ninjas in order to search for the Shuriken of the End. Being the only available ninja left, NinjaRed and HurricaneRed face him and Takaharu from the future assisted them in the battle. As Nekomata got the Shuriken and tried to return to the future, AkaNinger tried to hold him off but was seemingly killed in the battle. What remained of AkaNinger was kept by Sasuke, which was his burnt report card.
AoNinger doesn't believe it, even when the returned Nekomata confirms his demise. But Takaharu reveals himself to be alive, having used the Substitution Technique to fake his death and quietly sneak into Nekomata's time door. After destroying Nekomata, two Sealing Shuriken transform into Legend Nin Shurikens that represent the Ninningers' Sentai Ninja predecessors. Kyuemon realizes that what he got was NinjaRed's signature Shuriken instead of Yoshitaka's End Shuriken.
Kyuemon summons Giant Youkai Gashadokuro again before leaving as the Ninningers summon their OtomoNins to form Shurikenjin. Under NinjaRed's advice, AkaNinger uses his newly received Nin Shuriken before finishing off Gashadokuro.
NinjaRed and HurricaneRed leave the Ninningers on their own. They reunite with Akarenger as Yoshitaka thanks them for teaching his grandchildren while asking the Sentai Reds to look after them. Akarenger agrees, having watched over various teams of Super Sentai for years and witnessing the Ninningers from afar.

- While not the most recent appearance of Sasuke in Sentai (due to Hyakujuu Sentai Gaoranger vs. Super Sentai and the Legend War), this is the first time Teruaki Ogawa has portrayed Sasuke out-of-suit since Chouriki Sentai Ohranger: Ole vs. Kakuranger nearly 20 years prior in the very first VS movie, though he did voice him in Gokaiger Goseiger Super Sentai 199 Hero Great Battle.
- This is the second television Sentai team-up between the active team and members of a previous team(s), the first was in Gokaiger's Shushuuto The Special.
- Yousuke Shiina appears in both.
- As of this episode, HurricaneYellow is now the only Hurricaneger who has not returned for a team-up between the current Sentai and individual veterans from at least two different series without his other teammates (HurricaneBlue returned with AbareBlack, DekaBreak, MagiYellow, and MagiShine in GoGo Sentai Boukenger vs. Super Sentai, while HurricaneRed returned with Akarenger and NinjaRed in this episode).
- The mecha battle is similar to a Gokaiger tribute episode, as the Ninningers use a "special power" that the veteran rangers gave them, all while the score of the veterans' series is played in the background.
- This episode celebrates the 40th anniversary of Super Sentai (although Ninninger is the 39th series of the franchise, not the 40th).
- This episode is similar to Zyuden Sentai Kyoryuger vs. Go-Busters, because the two previous red rangers from series with the same motif of the current one appear unmorphed and fight alongside the "new" team. The main differences are that the red rangers are the only ones who represent their teams and that there isn't another team involved in the special (whereas the Go-Busters were in the dinosaur movie).
- Simillar to Geki's transformation scene in the movie, Sasuke also receives a 21st century era style transformation morph. This was probably also done to match up with the other two modern day Ninja Sentai teams.
- When Sasuke and Yousuke teach the Ninningers about what a ninja is supposed to be, they quote the last part of their respective team's roll-call.
- The opening credits are updated to include Paonmaru and UFOmaru.
- Ironically, while Sasuke and Yousuke acted cold and mature towards the Ninningers, especially Takaharu, they were however also air-headed and reckless back during their early days in their respective Sentai teams, just like Takaharu.
- This is further reinforced with the comparison between Sasuke and Takaharu in how they both have a running gag of being frequently scolded by the female Ninja Sentai White Ranger of their team.
- At one point, Yousuke chastises Yakumo for using magic to use an air technique, an ironic statement as the year Nekomata and Takaharu travel in time to was 2005, the year that aired Mahou Sentai Magiranger. Not only were they the last team composed of members of one family before Ninninger, but they were also are a team composed completely of magicians like Yakumo, one of them being a utilizer of wind magic. In a twist, it is later revealed that Yakumo took lessons from a member of the Ozu family.
- The Ninningers' second Super Hero Time partner, Kamen Rider Ghost, would later jump back in time by ten years while crossing over with somebody.
