2.5-jigen no Ririsa

After a disastrous romantic confession, Masamune Okumura finds solace in the fictional world of anime and manga. Now a second-year high school student and the president of the Manga Research Club, Masamune spends a peaceful existence watching the adventures of the angel Liliel, his favorite character.

In the beginning of the academic year, Masamune’s life is turned upside down when he meets first-year student Ririsa Amano, a passionate cosplay practitioner. Despite Masamune's initial reluctance, the determined young woman manages to convince him to become her personal photographer for the production of a collection dedicated to their common favorite character: Liliel.

As Masamune enthusiastically discovers the world of cosplay and photo editing, he is unexpectedly reunited with his childhood friend Mikari Tachibana, who has become a model in the hope of impressing her beloved upperclassman. Realizing that modeling is not enough to intrigue the hopeless otaku, Mikari decides to join the club and become a cosplayer herself, all to finally have a chance at winning Masamune's heart. However, Masamune's love for fictional characters may not be capable of extending to those who impersonate them.

I really loved the anime especially when we know that all characters are going and running from smth that they truly want... Mc running from past, misaki choosing to be actor but still hiding her feelings while Ririsa being only one fighting hardest for dreams and obviously mc being fking best support system u can ever get... Though majority anime community like misaki but i love Ririsa maybe bcos of short hair? Better development with mc? Better scenes of her and mc feelings? Better commitment to goals? Or should I say she is really really very beautiful and attractive...
Plot is okish and i enjoyed ... whole anime cos of scenes of Ririsa only....
Character development is great like everyone in this anime grows lil by lil bit surely mc might be living in past but still chad and reliable and mayura and her friend and even the fking principal and his philosophical words for his students are top notch... Overall good anime, also
RIRISA AMANO SUPREMACY ❤️

Mixed Feelings

An anime that is entertaining but nothing more, the premise of the otaku obsessed with his favorite work is fine but it didn't go deeper and many ideas that were good weren't exploited a little more, the cosplay designs were creative but not very showy, I liked that they came from different video games within the anime, the plot in some points is heavy and it's hard to watch the anime, as for the characters, the design of the protagonist is the model of any girls' or harem anime and the design of the girls is not that great, I also feel that their arcs ... sometimes fail to convey what they really want, that's why it's ridiculous to make a comparison of this anime with Sono Bisque Doll.

2.5-jigen no Ririsa had an interesting premise—a story blending 2D and 3D idol culture with romance. Unfortunately, it fails to capitalize on its unique concept, instead delivering a dull and predictable experience.

The biggest flaw is the writing. The characters feel one-dimensional, with shallow development that makes it hard to care about their relationships. The romance lacks chemistry, and the drama feels forced rather than engaging. The pacing is also inconsistent, dragging in places where it should be building tension.

Visually, the anime is passable but uninspired. The character designs are decent, but the animation quality fluctuates, making certain scenes awkward to watch. The music, which should ... be a highlight in an idol-themed series, is forgettable and doesn’t leave a lasting impact.

Overall, 2.5-jigen no Ririsa is a disappointing watch that doesn’t bring anything new or exciting to the table. Unless you’re a die-hard fan of the genre, it’s not worth the time.
