Group Information
Groups Obsidian


Takashi Agera is a young high school student from Radiant Heart Academy who interns at Obsidian's headquarters downtown. Or, at least, that's what most people think. But those within Obsidian know him as more than an intern, but as an innately talented Dark Energy user and researcher who is rising through the ranks of the organization fast enough to ruffle more than a few feathers. And, when it's time to roll up his sleeves and get to 'field work', Takashi is also Riventon, the dark-energy wielding Device User that is responsible for a lot of plans that would be smart if they weren't so reckless. Takashi is seeking power and respect, and his innate talent with Dark Energy seems to indicate he's doing more than just channeling it through his device.

Are you in?
Texts: still alive December 4th, 2023 Takashi texts Mamoru to ask if Sailor Moon killed him. Mamoru texts Usagi to see if she's okay and whether or not she killed one of the Witches 5. It's a whole thing.

Texting with Takashi and Mami: On Magic and Death October 29th, 2023 Mami lets Takashi know that Norie knows about them dating, and the conversation veers into Puella 101. Dating as magical boys and girls is rough.
Wanting It To Be A Good Idea October 27th, 2023 Mami and Takashi go on a date. There is tiny food and teas and walks home. And a continued lack of reasonable decision making skills.

Cold Coffee October 20th, 2023 Riventon owes Naru Who Knows a coffee meetup, and could use some good publicity.

The Cat and the Crystal October 14th, 2023 Catra plans an attack in Shibuya Crossing, with Riventon ready to back her up -- or maybe just to get the Pureheart Crystal.

Strawberry Blender Sneak Attack September 14th, 2023 Michiru goes out to find trouble, and she finds way more than she expected. Firefly has a new glaive, and it sure does look terrifyingly familiar!
Texts: The Prince of High School, Vol. 13 September 14th, 2023 Mamoru's phone is a little busy today. What with Naru wanting him to relay messages. And Takashi having a quibble with a senshi. And Usagi fussing. And ... Luna? And a DATE?

This Really Sucks July 22nd, 2023 Riventon summons a youma that is more dangerous that it looks, which is good because it looks ridiculous, and Cure Daybreak, Yellow Pearl Voice, Snow Agel Mou Foubiki, Amy Faust, and Ginga Otome all respond, fending off Osouji, Riventon, and Firefly; purifying the youma, preventing further damage, and sending the two home largely empty-handed.
Office Hours 9 -- Takashi July 21st, 2023 Takashi's in trouble. Only Inai-sensei has a different lesson than he expected.
The Cabin for Gifted Individuals July 19th, 2023 Riventon comes across a strange, abandoned cabin outside the city.

Probably not.

The Greatest Girl

  • Mami Tomoe - She shot me but it turns out she's hot and I'm hot so that's okay and now we're making all sorts of bad decisions together, it's great.

Found Family

  • Darien Shields (Adopted Sorta-Brother)
  • Hotaru Tomoe - (Adopted Kinda-Little Sister)
  • Pyrite - (What is it when your brother's sister isn't your sister but IS your brother's sister - ah whatever)

Faithful Friends

  • Yochu - (Adopted Kinda-Little Sister's Best Friend)
  • Feito - The most effective member of any sortie team I've left with. Also her mother is kinda mean.

Fabulous Frenemies

  • Zoisite - No matter what, we killed it at that dance.
  • Nephrite - Thinks big, hair's big.
  • Jadeite - I appreciate his mind for business.
  • Sunbreaker - We could accomplish so much more, if she'd just do everything I said.

Acceptable Acquaintances

Fuzzy Feelings

Sparkle Skirts (we do not like them)

  • Ginga Otome - I decided her small magic robot was mine but she still maintains control of it. Rude.
  • Kyouko Sakura - She stabbed me and I didn't even do anything wrong.
  • Homura Akemi - She gave me a pipe bomb. It was armed.
  • Cure Peace - She electrocuted me.
  • Nanoha Takamachi - One half of the Shock Rifle Combo that broke my hand and made me fix my device. See if I'm nice to ten year olds ever again.
  • Hannah Steiner - The other half. See if I'm nice to Space Germans ever again.
