Kazumitsu Tendo

Kasumitsu Tendo was killed by his sister Kisara Tendo during a duel. Kasumitsu Tendo is the cause of the the Third Kanto Battle, more specifically, he is the cause of monolith 32 collapsing. Kasumitsu is the Vice Minister of Land, Infrastructure, Transport and Tourism, LITT. He built monolith 32, however he skimped out on making it a pure Varanium monolith, adding in filler material to save money, therefore Alderbaran was able to hang onto it due to the weak magnetic energy emitted.
