Welcome
It just started airing Thursday, but might want to check out Peach Boy Riverside (the title is a reference to the japanese folktake of Momotaro). The setting feels like it will be similar to Tensura. And the 1st ep makes me think the MC has an OP berserker mode she goes into.
A couple other shounen I enjoyed but you don’t hear much about are Buso Renkin and Ushio & Tora.
