BASIL's HEADSPACE counterpart is rather cheery, yet shy and humble. He is quick to forgive, as can be seen by his encounter with BOSS after hide-and-seek, and he is very empathetic. He's quite friendly, and his shyness seems to stem from thinking lowly of himself and putting others' needs above his own.

He's very sentimental, keeping memorabilia of his friends and happy memories through photos, and planting flowers that remind him of his friends, taking great care to plant flowers with flower language corresponding to how he sees his friends. His empathy stretches to his plants as well, showing a lot of worries when they're in danger of being hurt, and talking to them as he would with his friends. It is noted that he avoids conflict. He doesn't learn to battle, even after his friends nag him to.
