Daily life with jobless, virgin, NEET sextuplets.
Characters
20s / Male / Eldest Personality: A NEET with the mental age of an elementary schooler and a naive streak. A fool with intense emotions, he's lazy and hard to pin down. He pouts if he feels ignored. Inner Self: He often teases or annoys his younger brothers, but he does care for them. Despite being expressive on the surface, he rarely reveals his true inner thoughts. Likes: Pachinko, horse racing, girls
20s / Male / Second Son Personality: Tries to be cool, speaks in a deep voice, and constantly says cringeworthy things without hesitation. Despite his act, he's actually a crybaby and the kindest, most sensitive brother. He's stuck in a 'chuunibyou' phase, always posturing and acting tough. Traits: Often ignored by his brothers and rarely treated like an older sibling. Frequently uses simple English words. Unpopular with women due to his painful fashion sense. Likes: Sunglasses, fishing, himself, girls
20s / Male / Third Son Personality: Basically a serious otaku youth. He looks like the only normal one, but he's just as crazy as the rest. He's the primary 'straight man' (tsukkomi) and has a very foul mouth. He has tsundere tendencies, is a bit of a clean freak, and has a high sense of self-consciousness. Traits: A hardcore fan of Nyaa-chan, a cat-themed live idol. He also seems interested in anime. Likes: Nyaa-chan, girls
20s / Male / Fourth Son Personality: Operates at his own pace and is incredibly lazy, though he denies being a loner. He has low self-esteem and is self-deprecating. A dangerous guy who whispers with half-closed eyes. Traits: Loves cats. Has both sadistic and masochistic tendencies. Calls Karamatsu "Kusomatsu" (Shitmatsu). While blunter than the others, he expresses his emotions clearly depending on the atmosphere. Likes: Cats, girls
20s / Male / Fifth Son Personality: A complete eccentric and a weirdo. Loud and always wanting to stand out. Despite being crazy, he's kind-hearted. He's a natural airhead with a permanent vacant expression. Traits: Loves baseball and pro-wrestling. Wears oversized sleeves (moe sleeves) and shorts. Likes: Baseball, girls
20s / Male / Youngest Personality: Appears pampered and cute on the outside, but inside, he's a calculating, meticulous, and cunning "Dry Monster." He has a bit of a devilish streak. Traits: Relatively popular with women. He pretends not to know his brothers when he's out in public because he's embarrassed by them. Has a great sense of fashion and is the only one who owns a smartphone. Likes: Taking selfies, girls
