Summon Night Ex-These: Yoake no Tsubasa is a spin-off in the Summon Night franchise. It was the series first attempt at an Action RPG. It was released for Playstation 2 in 2005.
Summon Night Gran-These: Horobi no Tsurugi to Yakusoku no Kishi a Role-Playing game, developed by Flight-Plan and published by Bandai Namco Games, which was released in Japan in 2010.
- Elemental RockPaperScissors: An oddity for the series, Gran-These has one. Coincidentally, it follows the cycle from Fire Emblem. That is, Light → Dark → Anima → Light. Anima also has its own internal cycle of Water → Fire → Air → Earth.
- Guys Smash, Girls Shoot: In Gran-These, Lost uses a sword while Millet uses a gun. EX-These has a lesser version: Leonus uses a two-handed sword while Ainna uses a rapier.
- Schrödinger's Player Character: Notably averted considering the rest of series (except the first Summon Night due to Early Installment Weirdness) follows it. The choice of protagonist in both EX-These and Gran-These is a POV thing. You can switch protagonists in EX-These with the press of a button.
- Spell My Name with an "S": EX-These has been rendered as "Ecstasy" and "EX-Thesis". To be fair, it was a change from Flight-Plan's usual Gratuitous English where a transliteration could easily be found in the game or the website. Only various books related to the game had it until the series' 10th anniversary celebration. Even there, it was hidden in the background image of the commemoration site. Not to mention the site's navigational display was obscuring it. This meant to see it, one had to stop the page before it finished loading; no easy feat as Japan has the best overall internet speeds in the world. The updated commemoration site has since changed to make it more easily visible.
- 夜明けの翼 (the subtitle of EX-These) is sometimes erroneously transliterated as "youaku no tsubasa" rather than the correct "youake no tsubasa". This likely has its origin in the scene release group GANT, whose release had the error (along with the "EX-Thesis" spelling), and spread as P2P copied it. GameFAQs had the error at one point, but was later corrected.
- Video Game 3D Leap: Gran-These.
- Zettai Ryouiki: The female leads of both games.
