OreGairu: A Romantic Comedy Hikigaya Never Saw Coming
Hikigaya Hachiman, a high school student devoted to the survival philosophy of "solitary supremacy," dreams of passing his days in peace. However, a smug little brat of a system calling itself "Rion," forcibly binds itself to him.
Not only does it mock his "dead-fish-eye survival doctrine" around the clock, but it also loves to pop up with "harem-crisis alerts" and "romance-assist skills" whenever his relationships with girls grow delicate.
And so, his daily life completely shatters—
His calm, sharp-witted childhood friend Yukinoshita Yukino begins to tacitly permit his "greedy" companionship.
The warm, genki Yuigahama Yui surrounds him with unreserved support.
Touma Kazusa, the clumsy, dependent piano prodigy, entrusts her entire heart to him along with the old piano keys.
Miura Yumiko, the blunt, tsundere queen of the in-crowd, loudly declares her intent to seize the position of "legal wife."
Kawasaki Saki, the reliable classmate who is cold on the outside yet warm within, quietly learns to rely on him.
Even Kirisu Mafuyu, the strict and awkward teacher, and Sawamura Spencer Eriri, the artist hiding her otaku nature, are quietly swept into the magnificent voyage of his youth.
This is a super-sized youth romantic comedy, brought about by a system's "malice" and a cast of girls who all "invited themselves aboard." And Hikigaya Hachiman's one and only task is to find, amidst the system's teasing and the maidens' "siege," a happiness that is his own—complex, yet genuine.
