- Godzilla Threshold: Due to the unstable nature of his Balance Breaker, there was initially a possibility that Tobio could lose control of himself while using it, thus forcing him to use it as a last resort and only with the assistance of his grandmother's prayer beads, which allowed him a limited amount of control over it for 10 seconds,
- Hero of Another Story: Slash Dog is the name of Ishibumi's second light novel and more details about his story are found there.

He really does love Sae, but Lavinia's wish of having a more playful relationship with him, coupled with Natsume's determination to accompany him and Suzaku's insistence to marry him muddies his stance further.
