- Inverted in episode 12 which takes place on July 7th, 2001, the same day as the Japanese festival Tanabata with no one being at Seiko's birthday party since she didn't come home at 7pm, which led to Nozomi going to her friend Haruka, Mamoru at the cash register ended up being distraught via a trigger (either someone asking to go to the bathroom or the Amber Crystal invitation he had in his wallet) remembering Seiko's words showing a flashback of one of the two episode 11 (Broadcast or DVD version are different plots) leading him to breakdown and ended up in the arcade and the birthday cake was not purchased. Dai saw Seiko with another man, ironically he joked about a potential affair previous episodes. Additionally both Nozomi and Mamoru refused to call Seiko while Dai was unavailable to call. As a result, Seiko scrambled to at least get Dai in the mission but she mistook Dai on top of the bridge's railings as potentially him wanting to fall down the bridge. Dai ended up pissing on Seiko and Dai is still pissed off at her for what he had just witnessed. Lastly Dai decided to try to kill himself by mounting on the Big Bang Crusher but luckily Ellen saved him but at the cost of her being on the receiving end by breathing the pollen that is coming out of the Giant Flower that is being destroyed by the Big Bang Crusher.
- Both episodes had a Giant Alien Plant extract soil from both the Dzhungar desert, China and in Tokyo, Japan. The former led to it becoming an actual desert lacking the grasslands it had previously.
- Episode 13: Ellen is revealed to be sick from the pollen that she breathed from the previous episode and Mamoru's boss says if he does not submit the report on the new development project today, he would be fired which is what ended up happening.

However, the aftermath as shown in episode 13 did lead to a miracle where the Daichi family were able to coordinate properly as a family while defend the earth and being under budget meaning that the mission is a success for the first time. Seiko, Mamoru and Nozomi for the first time together performed a finishing combination attack via gravity free kick on the dust trapped Giant flower by directing her onto the UFO's bottom eye. Dai saved Ellen's life by finding the cure inside of the Giant Flower while also helping her understand what a family is as she is in the brink of tears.

Video Games
- Bloodstained: Ritual of the Night: The Optional Boss Millionaire's Bane is a living slot machine. Near the end of the fight, it starts spinning the slots, attacking you based on the results.

- Final Fantasy IX contains the attack "Lucky 7s", a Shout-Out to the above.

- The seven Princesses of Heart are a group of seven young maidens whose hearts are completely devoid of darkness, those being Snow White, Cinderella, Alice, Aurora, Belle, Jasmine, and Kairi.

Kingdom Hearts 3D [Dream Drop Distance] reveals that their hearts were born from the seven fragments of light from the χ-blade. When faced against thirteen beings with hearts of darkness, namely Xehanort's Organization XIII, the resulting clash will recreate the χ-blade, which is exactly what Xehanort seeks. To protect the Princesses, the heroes decide to assemble seven Keyblade wielders as the Guardians of Light, even though they know that they are still playing into Xehanort's hands.

- In Sonic Chaos, finishing an Act with a calculated speed of 777km/h will award an extra life.

Its successor, the Crazy 8, spawns eight items to use at once.
- Mario Party:
- Rolling either a double 7 or triple 7 in most installments will give you more coins than if you rolled the same of any other number, though the payout varies by game.

Mario Party 8 ups the ante by giving you a cool 100 coins for triple 7's.
