Ultraman (2011 Manga)

A young Idol around Shinjiro's age, Rena became a fan of Shinjiro's after his numerous crime fighting exploits wearing his Ultraman suit. While her agent just denounced him a cosplayer, Rena was quick to defend him as the real thing. While on their way to an appointment, the two were stuck in a strange traffic jam caused by Shinjiro's battle with another alien. The pair landed nearby with Shinjiro landing on the hood of their car. While the alien belittled Shinjiro and destroyed his confidence, Rena and her agent had snuck out of the car. Hearing her hero being trash-talked, Rena called out Ultraman and gave him back his confidence. Unfortunately, this angered the petty alien who fired Plasma bombs at her. Fortunately, Shinjiro was able to stop the attacks with his Light Swords.

After the battle, she went to the hospital to be treated for minor injuries when she ran into her dad Endo, who was relived she was alright. Unknown to either of them, the four-eyed alien watched them drooling from outside.

Later, she appeared on TV talking with a news anchorman about the recent alien battle and whether the Earth was being targeted again by aliens. Rena was a staunch supporter of Shinjiro declaring that he was 'Ultraman' not a pretender.

During one of her concerts, a mysterious man appeared on stage behind her, claiming that he would kill her. The man then revealed himself as Adad, and he said that he would also kill the audience when he was finished. Shinjiro and Moroboshi appeared in their Ultraman Suits, causing Rena to be amazed that there was a second Ultraman.
