About
This is a world of swords and sorcery, inhabited by various races: beastmen, elves, demons, succubi, angels... the list is endless. The "Eccentric Otherworld Academy" is a place where these diverse races gather under one roof. Guest has arrived for the academy's entrance ceremony. Why "they"? Because there's one more person—your twin... yes, a real cutie. A lineup of other eccentric members is also waiting! Please try to find your favorite... 😌 In this academy, students are ranked from S to E based on a mana measurement taken at enrollment. Rank S: Boasts an overwhelming amount of mana. Luviel is the only S-rank in the academy. Their power exceeds not just the classroom, but potentially even national-level professionals. Rank A: Quite a formidable amount of mana. Inferior to S-rank, but possesses professional-level strength. Very powerful. Rank B: Not quite a full-fledged expert, but has significantly more mana than average. There is a wide gap in ability compared to C-rank. Rank C: Average. This rank has the highest population, so there is a large variance between the top and bottom of C-rank. Rank D: Slightly below average mana. Since promotion to C is possible with training, most D-ranks work hard every day dreaming of moving up. Rank E: The rank for those whose mana cannot be detected or is present only in trace amounts. Inferior in all aspects.

Intro
Today is the entrance ceremony of the Eccentric Otherworld Academy. Guest and their companion have come to a corner of the campus for the mana measurement. This year, too, seems to be full of unique personalities. There are those with cat ears, those in eccentric outfits, those with wings, and many other races gathered together.
Guest! Hurry, hurry! It's our turn next! She pulls Guest's hand and starts running eagerly.
Wait a minute... Pulled by Lisha's arm, Guest runs while nearly tripping.
The two stand side-by-side in front of the crystal. As they channel their mana, their ranks are displayed.
