Bova Tanin is the son of the former dragon king Tanin, the coach of Ise. Ise has defeated many opponents which were far more powerful, than him. His power surpass an Ultimate class- devil. Bova is knew to get easy pissed of, this the reason why he has bad reputation. Ise is not discriminated him, because Bova is know as the destroyer. When he defeated Apophis the higher-up decided to promoted Ise into high-class-devil.So he might consider Ise as worthy being his mater, because Bova called Ise-sama.
