Ein (エクセル Ekuseru ), also known as Ecthel, is the main protagonist of Riviera: The Promised Land. He is a Grim Angel of great potential and wields a Diviner, the sword Einherjar. He, along with Ledah, is sent to Riviera by Hector to activate the Retribution. In the story, he manages to keep up with Ledah with a little help from Rose despite the fact that he's new to his job. He is later separated from his two initial companions Ledah and Rose by Riviera's guardian, Ursula. She then gives Ein amnesia and drops him in Elendia so that he can better consider their point of view. After she gives him his memories back, he willingly allies himself with her.
Ein traded his wings for his Diviner, Einherjar. Ein is able to learn Double Slash as an Over Skill at the start of the game but it is later replaced by his signature move, Disaresta which breaks the Overdrive Meter.
He is voiced by Kugimiya Rie in Japan and Yuri Lowenthal in the PSP release.
Ein wears a blue cloak and wears blue shorts, and has brown hair. He also wears brown gloves, and has brown eyes. He appears to be 16 - 17 years old.
Much of Ein's personality is up to the player's direction and dialogue choices, but his default demeanor is innocent and friendly; he believes the best of everyone around him, even (to a point) his enemies. Many of the other characters remark on how naive and hopeless he is. Ein is quiet, usually speaking at times when necessary. During particular scenes in the game, he is said to be perverted, however this is usually mistaken though the player can make Ein as such.
Ein is a mandatory presence in every non-practice battle.
Ein's main selling point is his access to Disaresta. He can also use the support item Flag to rapidly boost the Overdrive meter. Otherwise, Ein performs best with sword-type weapons, and is able to use Lv. 3 Over Skills with them. His Over Skill with the Zephyr, Mimic Ray, is one of the most useful in the game with strong group healing and good damage. Ein has the second highest HP in the game, though still much less than Cierra. With high Darkness resistance, slight Physical resistance, and no glaring weaknesses, he is generally the best character at taking physical attacks. Ein also has good weapon compatibility with his teammates, and can use all of their specialty weapons. Ein is the only character immune to Sleep. However, Ein is ironically otherwise quite unremarkable in battle compared to his female companions. As with Serene, Ein suffers from having many magic-based Over Skills that deal poor damage. His Normal Skills are questionable as well, with only the sword Normal Skill being consistently useful. His spear Normal Skill, while striking the whole enemy party, has a high miss rate. He also has no resistance to the Poison status, which is troublesome against enemies like Skeletons. Finally, his low MGC makes him take huge damage from some dangerous magic attacks (most notably Angelic Thunder and Nightmare Waltz).
- Ein's stats decreased greatly upon his arrival in Elendia, due to the loss of the Immoral Rosary. He also lost his status immunities (other than innate ones like Sleep and Purify).
- Some fans hold his birthday to be July 10, the release date of the PSP version in America.
- The opening cinematic depicts a Grim Angel that strongly resembles an older-looking Ein with longer hair. The unidentified Grim Angel even has a similar-looking Diviner.
