Material Days/YMMV
- Chaotic Good: Material S with her being the only one who noted Yuuno's stress and fatigue, is very considerate of his feelings, and their first time was a result of mutual consent. But one cannot forget how she killed Fan Dumb Avatars in cold blood although she did come to regret her actions.
- Chaotic Neutral: Material L with the sheer atrocities she did, in the name of Cloudcuckoolander and For the Lulz. Sometimes, it may cross Dude, Not Funny territory, but most of the fans still like her and she did Heroic things at times. As her personality is based off of Deadpool, she'll also be bouncing around Chaotic Evil and Chaotic Stupid alignments too.
- Crazy Awesome: Material-L's characterization draws strongly from Deadpool, including being the Fourth Wall Observer.
- Hate Fic: Towards much of the fandom and the events of the series.
- Memetic Sex God: Touma, Touma, Touma.
- To a lesser extent, Yuuno himself. Scoring three girls in several days time span with at least one case that was somewhat against his will.
- Reactionary Fantasy
- Toy Ship: Not sure if it's qualifies (or even could be considered official), but Einhart Stratos sure wants to be with Touma Avenir (at least for now). At this point in the timeline, they're both 14 or 15 years old.
- Einhart, due to the memory of her ancestor, has strong feelings for Vivio.
- True Neutral: Material D She will do ANYTHING for the safety of her sisters, including Brainwash (or something) Yuuno into 'properly' taking care of them. Note that she does genuinely care for Yuuno, and she's more socially awkward than even Material S.
