I Transmigrated as Yagami Taichi, and I Don't Have a Sister

I transmigrated into Digimon as Taichi Yagami, but...

"I don't even have a little sister! Where's my Hikari?"

"Calm down, Taichi. You've still got me," said the Veedramon.

"In this cold, heartless world, only Hikari's embrace can make me feel a little warmth." Taichi hugged Gabumon.

Gabumon, known as Gaba: "...Just say you want to snuggle up to my fur."
