Synopsis

In a world where Western and Asian cultures mix together, the only son of Count Kikunoi from the Kiryuu Empire, is Ageha. His life was already over at the age of 5. He, who was born in a corner of the country, has zero allies or useful skills in addition to being overweight. What's more, it seems that his brother Regulus, who suddenly appeared on his life and was presented for the Count as his brother, will kill him in the future for his right to succeed...

His only weapons, are the abilities of "cooking and sewing," that he suddenly acquired along with the memories of his previous Japanese life. In the midst of all this, Ageha ends up raising his younger brother, but... "My brother is super cute?" And before he knows it, he becomes a full-blown doting older brother?!

Making handmade educational toys for his cute little brother and delicious chawanmushi (steamed egg custard)... With the help of his previous life's skills and my power as a housekeeper, he's able to improve the rough life of the people living in his territory. A fantasy of two young brothers managing their territory, where a single step gets even the gods involved in changing their country!

Preliminary (6/? eps)
I really wasn’t expecting to enjoy a series with the pillsbury doughboy as the main character, but it has been an enjoyable so far and it’s just chill and relaxing mostly. You can’t help but feel for the doughboy though, once his parents are introduced.

It shares similarities to Ascendance of a Bookworm, with it being a reincarnation based, the world possessing magic and taking place in childhood. However Neglected Noble is from the perspective of a male and one from a life of privilege versus being a commoner girl. Both share using knowledge from their previous life to make changes to their current world, ...

Preliminary (5/? eps)
I'm about five episodes in so far, and this show is surprisingly charming. A lot of the more annoying isekai tropes are absent, and the main character is very likeable -- you really feel for him when certain circumstances become apparent. Even though he has his isekai perspective, real events still hit him in a real way. Also, the elf teacher is honestly a delight. I'm going to keep watching.

The art isn't anything special, but this isn't an action series, and the expressions are rendered well enough. No one is wearing wildly inappropriate or anachronistic clothes. The MC does look a little weird. He's meant ...

I didn’t expect this anime to hit me so hard.

At first, I thought it would be another typical isekai — reincarnation, nobles, magic maybe. But Shirohiyo is something else entirely. It’s soft. It’s painful. And honestly, it’s beautiful.

The story follows a little boy, Ageha, who suddenly remembers his past life. He’s born into a cold noble family where no one really cares for him, but instead of giving up, he finds meaning in protecting his baby brother, Regulus. The twist? In his memories of the future, that same baby brother ends up killing him.

That alone set the emotional tone for me. Imagine being five years ...
