arceus_309★★★★☆EP 1You can tell they put a lot of work into the elven princess design and the way she acts all proper until the orc side of him takes over is hilarious
Demi-human races like elves, sirens, and dragons are facing extinction due to a shortage of males, and the government's solution is gloriously bureaucratic: a mandatory mating assistance program that randomly pairs human men with demi-human partners. Yes, it's exactly what it sounds like, and the show leans into it completely. The story follows Iris Thea Eaderlindt, an elven princess with an unusually open attitude toward humans, who transfers to Ark Metropolitan Academy, only to discover her assigned partner is her new teacher. That awkward first-day energy hits differently when paperwork requires reproduction. This 10-episode OVA from studio Majin blends urban fantasy world-building with its mature premise, giving the setting genuine texture through mythology and interspecies culture rather than just using the fantasy backdrop as decoration. The cast expands beyond Iris to include demi-humans from various mythological traditions, each with their own relationship to the program. If you've watched Monster Musume or Interspecies Reviewers and wanted something with a more structured narrative around the worldbuilding, this scratches a similar itch. It's adapted from manga, so the pacing moves with purpose across its episode count. Don't go in expecting a slow-burn romance. the premise is upfront about what it is. But if the urban fantasy angle and the mythology-meets-modern-bureaucracy setup sound interesting to you, there's more going on here than the premise might initially suggest.
This season covers Chapters 1-20 of the manga. Continue reading from Chapter 21.

arceus_309★★★★☆EP 1You can tell they put a lot of work into the elven princess design and the way she acts all proper until the orc side of him takes over is hilarious
xiangliyaos★★★☆☆EP 1Iris getting flustered when she realized his ancestry was cool and the animation stayed surprisingly consistent during the whole sequence in his office
bizzo_senpai★★★☆☆EP 1Part of me thought the mating program plot felt a bit rushed and I wish they spent more time on the school setting before jumping in
chika_fujiwara_162★★★★☆EP 1The elf princess looks so much better than the promotional art and that scene in the classroom was way more intense than you would expect from the start of the show
byakuya_of_the_dreams_253★★★★☆EP 1I thought the twist with the teacher having orc blood was cool because it explains why he can keep up with a princess and the art was super clean for the first scene
cilan_339★★★☆☆EP 1Iris is definitely a top tier elf character and the way she takes her royal responsibility so seriously even in this weird situation is pretty charming
sakura_strength★★☆☆☆EP 1It started out a bit slow with the world building, but the ending definitely picked up once the teacher and Iris finally got some time alone together.
vesper098★★★★☆EP 1the orc lineage twist actually explains a lot about the teacher and his stamina so it was a cool way to spice up a standard teacher student trope
piko_pixel★★★★☆EP 1the character designs for the other students in the classroom look promising and my favorite part was seeing how shocked iris got when she realized who her partner was
enenra_enigma_53★☆☆☆☆EP 1The pacing felt way too fast during the introduction and they barely explained how the matching system works before jumping straight into the fanservice stuff
isidro_the_thief★★★★☆EP 1iris being a total honor student while trying to figure out how to deal with her teacher was funny and the fantasy elements are actually integrated well
alder_326★★★★☆EP 1Iris acting all proper in the school hallway then switching to her duty as a princess in private is a great contrast and the animation actually looks decent
rubeus★★★☆☆EP 1I was mostly just curious about the setup of a human mating with different races to save them from extinction, but Iris being an elven princess adds a lot of pressure to the situation. The teacher having orc blood explains why he can keep up with her so well and it makes their dynamic pretty interesting for a first episode with how it balances the school setting.
mauka_maiden★★★★☆EP 1I did not expect the teacher being part orc to be the big reveal and it made the scenes with Iris way more intense than I thought they would be
tatl_264★★★☆☆EP 1the whole government program setup is pretty weird but the art style for the elf characters is nice enough to keep me watching for another episode
muso★★★★☆EP 1The metropolitan academy setting was a cool choice for an urban fantasy. I liked how they introduced the mating program right away
geeta_360★★★☆☆EP 1Iris is a lot more approachable than you would expect for a princess, and seeing her take the initiative with the teacher was a highlight
c_c_code★★☆☆☆EP 1It moves way too fast into the action without building up any real connection between Iris and the teacher and that felt a bit rushed for a first episode
ubagabi_usurper_93★★★☆☆EP 1I found the setup with the elven princess being paired with her own teacher pretty wild. The lore about the declining birth rates actually makes sense for the world
obariyon_oracle★★★☆☆EP 1That orc ancestry twist at the end really changed the vibe. The art from Studio Majin looks solid enough for this kind of plot
