Senichi Enari

"Three! Investigate using futuristic technology(Mitsu, mirai no kagaku de sousa) DekaGreen!"

- DekaGreen's roll call

Senichi Enari (江成 仙一) or "Sen-chan" (センちゃん), is DekaGreen (デカグリーン) of the S.P.D. and Dekarangers.

Dekaranger
Born in a poor family as one of seven siblings, he is the brains of the team with a remarkable ability to think things through. Oddly, he does his best thinking when he's upside down, calling this pose the "Thinking Pose." He has a fear of dark, enclosed spaces that was caused by an incident of falling into a well when he was younger. He was rescued by a policeman, who inspired him to work for the police department. Sen-chan usually maintains a calm, eccentric composure, but he is said to be pretty scary when he is angered. He mentions that he used to be a 'combi' with Gyoku Rou as did Jasmine and Hoji Tomasu and that they both used to argue with each other. But he forgot at first who Sen-chan was which hurt his feelings quite a bit which lead to Gyoku being punished by Umeko. Has a bit of a crush on Umeko, but never shows it outright. His number is 3.

Magiranger vs. Dekaranger
He and Umeko are now a couple, however he forgot about their date and she put him in a headlock.

Legend War
A few years later, Sen-chan fought alongside not only his own team, but every single Sentai ranger in existence, against the Empire of Zangyack when it attacked the Earth in the Great Legend War. After fighting against hundreds of Gormin and their Zgormin commanders. AkaRenger noticed the fleet moving towards them, he gathered all the Rangers together and gave them the order to sacrifice their powers to wipe out the first invasion's armada. Sen-chan is one of several rangers (portrayed by a stand-in) who could be seen in the background when the Goseigers awoke after sacrificing their powers.

Farewell Space Pirates
After the Zangyack Empire was defeated by the Gokaigers, Marvelous returned the Ranger Keys to their orginal owners. Sen'ichi and his teammates have their powers again.

Super Hero Taisen
Sen, alongside his team (DekaBreak, DekaMaster, and DekaSwan were absent), among the majority of the Super Sentai heroes, was caught up in the "Super Hero Taisen" incident which eventually resulted in the Super Sentai teams and Kamen Riders joining forces to defeat both Dai-Zangyack and Dai-Shocker. During the final battle, he is seen in the background fighting a Chap and Gecko Imagin.

Super Hero Taisen Z
The five Dekarangers are seen alongside the Flashmen, standing behind Space Sheriff Gavan Type G and Kamen Riders Fourze, Meteor, Decade and Super-1 as the three forces of super heroes confront Space Shocker. After was destroyed, the Dekarangers appeared on a cliff alongside all the other past heroes to say goodbye to the heroes of recent years before taking their leave.

The DekaGreen Ranger Key (デカグリーンレンジャーキー) is Sen'ichi Enari's personal Ranger Key and what became of his powers after he along with the rest of the 34 Super Sentai sacrificed their powers to end the Great Legend War.

This key along with the majority of the Ranger Keys were collected by the Red Pirates and later used by the Gokaigers. The DekaGreen Ranger Key was mainly used by Don Dogoier (Gokai Green), who used it to fight as DekaGreen.

The Dekaranger keys, along with all the Ranger Keys of the first 33 Super Sentai, were briefly taken by the Black Cross King and turned into Ranger puppets that were fought by the Gokaigers and the Goseigers. Splitting up, the puppet DekaGreen was defeated as part of a group of surviving Green and Black warrior keys by Gokai Green and Super Gosei Black.

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. Sen received his key and became DekaGreen once more.
