意味

Reincarnation — a core concept in isekai genre where a character dies and is reborn in another world.

転生 literally means 'reincarnation' but in modern otaku culture it is primarily associated with the isekai genre where protagonists die (often hit by a truck, known as トラック転生) and are reborn in a fantasy world. The term has expanded beyond fiction — fans joke about wanting to 転生 into their favorite anime world, and virtual content creators 'reincarnate' when they restart under a new identity.

1. 異世界に転生するなら何のスキルが欲しい？
2. またトラック転生ものかよ。
3. あのVTuber転生したらしいよ。
